Yes, there are questions and answers out there, but this is for VS 2022

I develop mainly BLAZOR Server applications at work. Beginning a couple updates ago, I've been getting this dialog:

Microsoft Visual Studio has detected that an operation is blocking user input. This can be caused by an active modal dialog or a task that needs to block user interaction. Would you like to shut down anyway?

This usually occurs while debugging and stepping through code. My first indication is when I can no longer hit F10 to step to the next line of code. Then I will notice after stopping the app I'm debugging, I can no longer edit my code, until I restart VS2022.

THERE ARE NO CONSOLE WINDOWS OPEN ANYWHERE, NO DIALOGS, NOTHING.

The solution I see this occurring mostly has 5 projects: 1 Blazor Server app, 2 .net 6 class library projects, 2 .net 6 console app projects.
The problem most often appears when debugging one of the console app projects.

This solution makes use of the following NuGet packages:
ClosedXML version 0.95.4
DynamicExpresso.Core, 2.12.0
Microsoft.AspNetCore.Authentication.Negotiate, 6.0.1
Microsoft.AspNetCore.Components.Forms, 6.0.1
Microsoft.Data.SqlClient, 3.1.0
Microsoft.EntityFrameworkCore, 6.0.4
Microsoft.EntityFrameworkCore.Relational, 6.0.4
Microsoft.EntityFrameworkCore.SqlServer, 6.0.4

Hi @Mark Miller , welcome to Microsoft Q&A forum. Do you have some extensions(third-party) installed and been using? Can you reproduce this issue in a simple newly created project maybe? If this issue is reproducible, could you share me the steps to reproduce and confirm this issue?

Same issue for me, completely different project. C# during debugging of a command-line application, I am looking into an intercepted exception. Modal dialog appears. Then I continue (the exception is printed on the console output of the app, the app terminates, "Press any key to close the window" appears, execution and debugger appear to finish.
The studio 2022 UI seems blocked by some (invisible) window, and the workaround is to exist Studio and start it again (which takes lots of time cause I have 2 hundreds+ of projects in my solution).

Hi @Artem Zarafyants ,

May I confirm whether this error appears at the same place after you restart VS and debug the application again? Or the error doesn’t appear after you restart VS, debug the application, but it appears randomly?

If you check the Task Manager, will you see any running process/dialog/window which may cause this error in the background?

Here are some suggestions for narrowing down this issue currently:

Repair VS from VS Installer and reset VS settings.

Update VS 2022.

Test your solution on another machine if possible.

If all the above methods don’t work, I suspect that the issue maybe hides in code/specific projects, would you mind sharing some detailed related information/code snippets to check further?

This started after the last Dev Studio 2022 update for me this week. Closing and reopening isn't fixing it as well.

I'm testing out Visual Studio 2026 Insider (11111.16) and this problem has become significantly more prevalent here for me. A few times a day.

After updating to visual studio 17.11.0 I get the same problem.

Only visual studio is open. No dialogs. No nothing.

It is UNACCEPTABLE that Microsoft can't provide more specific error messages when it's products report an issue. It's like the software produced by Microsoft is degenerating into timewasting garbage. This goes for office too, like "There was a problem opening the file" or "Failed to save file". I mean, what are we supposed to use these kind of error messages for?

Tried to report the same error, but the post gets deleted. Tried several times. Looks like the forum has something blocking too. So instead of posting here, I will post many times on many other forums instead, not to get help, but to show how Microsoft treats their users.

I'm on Visual Studio 2026, Version: 18.0.1. This issue has become more relevant now. It happens many times a day, specially when switching between git branches. I'm unable to build, or rebuild the solution I'm working on, unless I close and reopen Visual Studio.

Has anybody found a solution to this? It happens to me a couple times per day, there is no dialog, letter/number keys are unblocked, only navigation and modifier keys are blocked. It makes zero sense. I have no add-ins installed other than Red-Gate (maybe that's it?)

This is impacting most of our teams at my company. We're all waiting impatiently for a response / update from Microsoft. It's been happening for a while. And is a HUGE disruption for our workflow. Especially when using service fabric on machines that take a while to spin up. It can cost us several hours a day.

Completely unacceptable. If I start a company I'll be sure to stay far away from Microsoft.

I had the same problem, the keyboard didn't erase the code, but for me it was solved by updating Visual Studio 2022, and when the installer asked me to save the unsaved projects, it appeared that it had 2 "processes" running, the first one: The my project, and the second one that looked suspicious (possibly the reason for the error message): vshost. I'm not sure what the installer did, it probably closed it. And mainly, when the keyboard keys lock problem, whenever I tried to press a key, a Windows sound came out, anyway. Problem solved, but what would that problem be? I did install an extension, it's UnrealVS, as I remember it was an older version (probably it was for the 2015 version of Visual Studio).

I'm still having the same issue, and it seems to be related to the debugging option. I always need to close and reopen Visual Studio, that is very annoying. It seems to be random, I was not able to understand which is the sequence of actions that create this error, but I face it at least twice a day. Any suggestion will be really appreciated! Many thanks!

Same problem (selective keyboard issues/locking up). No dialogs or prompts open anywhere. Just updated VS2022 yesterday. Ignoring the warning and restarting VS2022 resolved for me.

Precipitating event: Added a new Console App to an existing solution (.NET 8.0 LTS, Do not use top-level statements ticked, Enable native AOT publish unticked), click Create. Immediately the keyboard seemingly had a stroke. Some letters would work but not backspace or control or control-F5 :/

I repeated these same actions twice to attempt to reproduce problem (both unsuccessful), but everybody likes random, and I'm sure the devs are as thrilled with this problem as the rest of us.

This has happened to me a number of times - VS 2022 just seems really buggy so far.

My keyboard stopped working so I couldn't type.

But closing and reopening fixes everything - but I get that error message every time I have to close when things stop working.

This has happened to me 3 times in this week already. Closing and Reopening a VS2022 works for me.

I'm using Version 17.3.5 VS2022 Professional.

I have been getting this randomly.

It blocks the Ctrl, Alt and shift keys. Very annoying. Dialog appears when trying to shut down. I attempted to kill VS subtasks one by one but no luck.

Microsoft Visual Studio 2022 has detected that an operation is blocking user input. This can be caused by an active modal dialog or a task that needs to block user interaction. Would you like to shut down anyway?
