Visual Studio 2022 has stopped showing errors and intellisense

Question

For the last 7 days Visual Studio 2022 no longer shows red squiggles under any errors in the IDE text editor and no errors in the Errors List window. If I try to build it fails and I can see the errors in the Output window, but no errors are listed in the Errors List window. It has also stopped showing or responding to any intellisense commands. I have the Show error squiggles option under Tools -> Options -> Text Editor -> General, enabled.

I've attached a screenshot and gif showing the problem

.

Hi @Dave Barnard , 

Welcome to Microsoft Q&A!

Please try the following:

1. Update your VS2022 to the latest version with Visual Studio Installer and launch it again.
2. Enter “devenv /ResetSettings” at Developer Command Prompt for VS 2022 to restore your Visual Studio default setting.
3. Close all running VS instances and delete the hidden .vs, bin and obj folders in the project folder.
4. Rebuild the project.
5. Create a new project and check that it works properly.
6. Ensure you are using "Build + IntelliSense" in the Error List window.

Sincerely,

Anna

I came here looking for a solution to the same thing. I have found if I change the view to Build only I can see the errors. If I have the view as Build + Intellisense then the errors do not show.

This has only recently started happening so possibly with a recent update?
