Microsoft.VisualStudio.Editor.Implementation.EditorPackage did not load correctly

Question

Microsoft.VisualStudio.Editor.Implementation.EditorPackage did not load correctly

YT 唐 15

When I start Vs, I will be prompted with such information:'Microsoft.VisualStudio.Editor.Implementation.EditorPackage did not load correctly', and noticed a log file named ActivityLog.xml.

I checked the errors occured with 'setsite failed for package [microsoft.visualstudio.editor.implementation.editorpackage]source: '(null)' description: unspecified error', guid:{E269B994-EF71-4CE0-8BCD-581C217372E8},Hr:0x80004003 - E_POINTER. But no more infomation.

I followed the advice mentioned in a long ago post: https://developercommunity.visualstudio.com/t/microsoftvisualstudioeditorimplementationeditorpac/47524

for example, completely uninstall and reinstall, change the installation location, and clear userdata, but none of them work.

This error is currently happening on all versions of vs2022, including the preview version, now I can only switch back to vs2019, only it works correctly.

This is killing me. Several months of the same issue. None of this helps.

I get this error-

SetSite failed for package [Microsoft.VisualStudio.Editor.Implementation.EditorPackage]Source: '(null)' Description: Unspecified error

And I am going round in circles trying to fix it.

Hi @P33tr ,

Please try following methods and let us know if it works:

Repair Visual Studio from VS Installer > More > Repair.

Open VS Developer Command Prompt and run devenv /SafeMode, check if the same error appears.

Rename/remove these two folders: C:\Users\{username}\AppData\Roaming\Microsoft\VisualStudio\17.0_xxxxxxxx, C:\Users\{username}\AppData\Local\Microsoft\VisualStudio\17.0_xxxxxxxx\ComponentModelCache, run VS as administrator.

I fixed my issue by the following steps

Remove the extension Github Copilot for Chat if installed as that was main culprit.

Close all VS instances

In File Explorer, browse to %localappdata%\microsoft and rename the VisualStudio folder to VisualStudio.old

In the Start Menu, type 2022 and you should see Developer Command Prompt for VS2022, open this and type devenv /resetsettings and try to run devenv /resetuserdata too but the second may not be necessary

Open Visual Studio and immediately go to Tools > Options > Accounts and uncheck Synchronize Visual Studio settings across devices and installs

This should hopefully solve all your issues, however, I had to do this a couple of times for it to completely stop.

You may have another extension causing this but mine was 100% copilot for chat

For now use Visual Studio 2019. As per observation, VS 2022 has bugs on templates for .net framework projects.

Try to use .net core projects in 2022 and let me know if you got the same errror.

I had the same issue and managed to fix it following Paul McCowat's suggested method.

I disabled all my extensions, then renamed the %localappdata%\microsoft folder, and in the Developer Command Prompt for VS2022 ran both devenv /resetsettings and then devenv /resetuserdata. Then I went into Visual Studio and unchecked the "Synchronize Visual Studio settings across devices and installs". After doing that, it has so far been running ok.

I suspect the problem is with the data in the cloud holding the synchronized settings. Once they get broken, if the local Visual Studio sync's down the settings it breaks. So you have to reset using "devenv /resetsettings" and then, as quickly as possible, turn off synchronisation before it has chance to do a first sync. If you're too slow, and it syncs, then you have to reset your settings and try again.

Hello @YT 唐,

Welcome to Microsoft Q&A forum.

In case this is a potential issue, I may recommend submitting a ticket on our Developer Community by using VS Installer > Provide Feedback > Report a problem for further investigate.

Currently, you may try following steps(if you haven’t tried):

Close VS and VS Installer > navigate to C:\Users\username\AppData\Local\Microsoft\VisualStudio\17.0_xxxxxxxx > rename ComponentModelCache folder(s) > run VS as administrator.
Run devenv /ResetSettings command in Developer Command Prompt for Visual Studio 2022 to reset VS and VS settings.

Sincerely,

Tianyu

This is happening to me also on both my laptop and PC so must be related to user profile. Tried steps 1 and 2 and a re-install but continues to cause issues including not being able to find and replace.

Hi @Paul McCowat ,

Hi, I was certain this was submitted to the Developer Community via Visual Studio

Opening as administrator still causes another issue I hadn't mentioned which is crashing when trying to edit Tools > Options > Text Editor > Razor properties

All the other issues are still there too, can't open Find / Replace window, no intellisense in .cshtml files.

Same issue. It started happening yesterday: VS closes almost immediately after startup. There isn't even enough time to interact with the UI.

I noticed there was an update, so I installed it and rebooted. VS ran for a short while yesterday afternoon after the update.

Today, with no other changes or system updates having been made, the problem started happening again.

I've included the exception stack trace portion of the Microsoft.VisualStudio.Default.err file.

Note that this also happens when I try running VS as an admin.

Also, FWIW, I've not installed any new extensions recently.

Hi @Ken McGowan,

These days, VS 2022 version 17.7 has been released, may I know if you update VS 2022 to the latest version, will this issue disappear?

My issue is still happening on 17.7

Can't open the Tools > options > Text editor > Razor without crashing

Find & Replace doesn't work at all.

Microsoft.VisualStudio.Editor.Implementation.EditorPackage error opening razor files and intellisense doesn't work

Hi @Paul McCowat ,

Does closing VS, renaming this folder: %localappdata%\Microsoft\VisualStudio and then restarting VS work?

It’s possible that this is potential issue. If you have reported this issue on our Developer Community, could you please share us the thread link for better tracking the issue(Developer Community should send you an email after you have submitted the problem, and the thread link is included in it)?

If you haven’t submitted a report ticket on Developer Community, could you please try to report this issue from VS Installer > Provide Feedback > Report a problem? As Developer Community supports collecting and attaching some system/VS/error information, it will be better for us to investigate further.

Feel free to contact us.

This worked and everything was great until I added Copilot for chat extension and the issues all came back so I will post on the Github issues for that extension.

What should I rename the folder to?

2023-09-06T07:59:36.1133333+00:00

Hi @Kilvny ,

You can rename the folder to any name, for example "XXXX_backup".

The purpose is to back up it and delete it, actually renaming is the same to "copying(make a backup) => rename the new folder(backup) => deleting the previous/old folder".

I have also encountered this issue, and resetting the user settings has no effect. The more serious issue is that when my UI interface is dark, the code editor bar displays white!

Hi @繁华摘,

If you try to run this command devenv /SafeMode in VS Developer Command Prompt, and create a new project, will the same error appear?

Does renaming this folder(%localappdata%\Microsoft\VisualStudio) work?

Besides, did you install any extension? Does this issue appear on every project, or it only appears on one specific project?
