"Feature 'XXX' is currently unavailable due to an internal error."

Nathan Sokalski 4,111

Visual Studio 2022 recently started (for absolutely no reason) displaying the following message(s) at the top of the Visual Studio 2022 window:

Feature 'Diagnostic analyzer runner' is currently unavailable due to an internal error.

Similar messages are displayed for many other features (the list is endless!). This started happening for no reason, I did not change (or even open) the settings or preferences, I did not create (or even edit) any files, I did not install any updates, I barely used my computer. Here is a screenshot of the messages:

If I close all the files, it sometimes lets me click the X on the right to get rid of the messages, but then they come back when I reopen the files. What is the problem? I have not tried to repair Visual Studio 2022 (that is, in my opinion, a last resort, since it doesn't always fix the problem). I currently have:

Microsoft Visual Studio Community 2022 (64-bit)
Version 17.0.4

Getting the same issue in 17.4.2 as of today. https://github.com/dotnet/roslyn/issues/58102

Same issue in version 17.4.2 popped up for me this week when I went to set up a new machine, so it seems the issue isn't fully resolved.

I'm not doing anything in particular when it happens. I open a solution i've worked in for years on a previous machine, VS2022 on that machine has no issues. After coding for a bit this will happen and my intellisense drops. After restart it will work again for a few minutes. Other, smaller solutions seem to work for longer but will also get the issue sometimes.

Fully fresh install of VS 2022, no extensions added. I even ran the InstallCleanup.exe step from here https://learn.microsoft.com/en-us/visualstudio/install/uninstall-visual-studio?view=vs-2022 to do a completely fresh install.

Since this is related to Microsoft.CodeAnalysis, could it somehow be the .net installation? Should I try to reinstall .NET 6 on my machine?

My only other idea is that there could be some policy on my machine that is causing the JSON-RPC call to not be allowed? I'm not sure what it's connecting to though so not sure what to look for there.

Thanks! I am building for Unity and I finally could find a workaround with going to 2017 version. At least I can continue working with syntax errors and references while Microsoft fixes this problem.

I have the exact same issue. It started only after updating visual Studio to 17.3.1. After multiple repairs, I found out that it is only triggered when one extension starts running. I managed to find the culprit in my case, but hasn't found a solution yet.

Visual Studio 22 Enterprise version 17.3.1

Try updating to 17.3.2 (https://learn.microsoft.com/en-us/visualstudio/releases/2022/release-notes#issues-addressed-in-this-release-of-1732).

I've been having the same issue since last Thursday. Suddenly I started getting multiple 'Feature xxx is currently unavailable due to an internal error.' messages. I'm using Visual Studio Professional 2022 (v17.4.1).

I tried a git clean, a repair of my VS installation, fully uninstalling and reinstalling VS, ...
The weird thing is that it happens in both of my git repositories containing my main solution, but not in the smaller solutions I work on.
I'm sure it has something to do to code analysis as I was toggling that on and off quite a few times Wednesday evening and the problems started on Thursday morning.

I have no idea how to fix this.

For me it got fixed by deleting some jquery files that came with a bootstrap project. Maybe VS2022 has some issue with some jquery plugin files??

Exactly same issue here with Visual Studio Enterprise 2022 (v17.4.1). Repair, full remove and reinstall didn't help.

VS 2022 just installed (last night/this morning 11/22/2022) and now I am having multiple messages about "unavailable". Didn't have this issue with 2019. Elsewhere Microsoft says it has identified the problem and that the message is a duplicate. Well, Microsoft has not fixed the problem. I doubt if they will. So how do we turn off these messages? If MS actually does fix it (they've known for over a year), when will we be notified?

Same issue with Visual Studio 2022 Enterprise 17.4.1 - I'm getting three of these "currently unavailable" messages and VS gives me no information to know what is wrong or how to fix it.

I'm having the same issue on VS 2022 v17.4.1. Not only that but VS has been chugging a LOT of RAM, like 99% and will sometimes crash my entire computer.

v17.4.2 released Nov 29, 2022 claims to have fixed:

"feature 'symbol search' is currently unavailable due to an internal error"

I wonder if it also fixes all the other feature errors. I just updated and i havent seen the error pop up yet.

This is out of hand--it is happening all the time now. I did a three-hour VS repair but it didn't help. Can someone please give an update?

R. Cooke 51

Started getting these messages after updating to 17.4.2 earlier this week.
Tried a repair on Visual Studio, have disabled all extensions. Neither helped.

Editing to add: I toggled off the highlighted options in Text Editor/C#/Advanced and it seems to have killed this specific error message. Fingers crossed.

Thanks for this! I've also applied same setting and so far so good.

Not sure if this is related, but I've noticed previously that every time I've crashed there are multiple Node.js threads left running in the background.
I've manually ended the tasks. These threads where not created once I've disabled the 2 settings in your screenshot.

Updated to VS Pro 2022, v17.5.0 this afternoon. Worked fine all afternoon. Closed VS, then reopened 5 minutes later it and now I'm having the same problem. Seems to happen regardless of what projects/solutions I open. VS is unusable when this happens. Intellisense, refactoring, all sorts of things have stopped working.

This started for me after I updated VS2022 to the latest version just last week.
I was using a quite old version (from last year sometime), so either these issues were always there, but the earlier version of VS2022 just didn't notify me about them, or the update introduced new issues.

Despite all the warning messages, everything seems to be working as normal. I certainly haven't noticed any features being missing or broken.

So, there is no way to fix this? I uninstalled everything, ran InstallCleanup (the utility), reinstalled (17.8), and the problem is still there.

@Andy Martin The problem is that I would have a ton to rollback. 17.8 released .net8 and I fully upgraded everything to that. I keep assuming a fix will come, but as of 17.8.2, nada.

The best feature with this feature is that whenever you press "Close" it comes back again and again, like that's exactly what I wanted. I wanted to close it because it does not "disrupt" anything currently. Then I see it again because it comes back. And then I close it again. In the end I get four of these lines taking up 10% of the height of my screen. As usual, very good Microsoft! Of course "closing the error" means give me the error! You have cracked the logic of the universe. Yes means whatever MS decides and no means whatever MS decides.

I'm having the same issue which just started today. I'm using VS 2022 Enterprise, version 17.12.0. Here are the 3 errors I'm getting when I click on the "Show Strack Trace":

I've reported this several times over the years. It gets 'fixed' ... but has never actually been fixed (or has regressed its way back). I get this multiple times per session and have to restart the ide each time. Highly, highly annoying. I've offered (and am offering) my full project source code if it will help resolve this 'truly.' I'm using Maui with Telerik controls, and quite a few packages.

Hey Microsoft Community,

You're definitely not alone — this error "Feature 'Diagnostic analyzer runner' is currently unavailable due to an internal error" (and similar ones) has frustrated many developers, especially when nothing was changed and it suddenly starts popping up across the top of Visual Studio 2022.

This kind of issue is often linked to corrupted cache data or background processes failing silently. It's bizarre, especially when you're not even actively working on anything. While closing and reopening files might offer temporary relief, the errors tend to return once the environment loads analyzers or extensions in the background.

Here are a few steps you might consider before resorting to a full repair:

1. Clear the Visual Studio Component Cache Go to %LocalAppData%\Microsoft\VisualStudio\17.0_xxxxx\ComponentModelCache Delete everything inside that folder. Restart Visual Studio.

2. Disable or Update Extensions Sometimes extensions silently break after minor updates to Visual Studio or Windows. Try launching with: devenv.exe /SafeMode to see if the problem disappears.

3. Check .editorconfig or .ruleset Files If these files have invalid entries, analyzers can crash. You said you didn’t edit files, but it’s worth checking for corruption or changes pushed by an update.

4. Run Visual Studio Installer > Modify > Repair (only as a last resort) As you mentioned, repairs can be hit or miss — but if all else fails, it might be necessary.

In the meantime, while Visual Studio is sorting itself out (or testing SafeMode), why not take a break and enjoy some good content? Sometimes stepping away from bugs is the best fix.

Thanks a lot!!

I finally resorted to using Repair, and it (supposedly) fixed it, so I guess I'm good for now, but just as a suggestion/reminder to others, if you can find any other way, use it, because as most of us know, reconfiguring all the settings & configuration of Visual Studio is a major pain, even if you do export & import the settings. I'll consider it fixed (or repaired) for now, but it would still be good to know what happened & how else I could have fixed it for the future.

I would do a repair on visual studio 2022. If it is still happening after you do the repair I would disable any visual studio extensions you have installed to see if that fixes the issue
