Question

Hi! I'm using VsiaulStudio 2022 Professional and recently getting annoying a dialog. It appears at every start up of VisualStudio. The dialog says

"Driver Testing

Could not load test information. Error: Could not load file or assembly 'TaefTestParser, Version=2.0.0.0. Culture=neutral, PublicToken=31bf3856ad364e35' or one of its dependencies. The system cannot find the file specified.."

If I push [OK] button and VS seems works. Around the same time, I've installed DirectX SDK (Jun 2010) but no idea it affect this issue. I've already re-installed Windows SDK (10.0.22621.0) that I use mostly and did "repair VisualStudio" on VS installer, but got no luck. How can I fix it?

Hi @copin clair , 

Welcome to Microsoft Q&A! 

Please update your VS2022 Professional via Visual Studio Installer. 

Then, launch it in Safe Mode (run devenv /SafeMode in Developer Command Prompt for VS 2022).

If the VS works fine in safe mode, it means that the error is caused by the installed extensions. You can temporarily disable or uninstall the installed extensions (especially WDK extension) under Extensions > Manage Extensions > Installed. 

Besides, you can also try to uninstall and reinstall the VS.

Sincerely,

Anna
