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?

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
Microsoft.EntityFrameworkCore.Tools, 6.0.4
System.DirectoryServices.AccountManagement, 6.0.0

Following is from the VS Help-About dialog:

    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.

    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.

    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).
