I've encountered a bug similar to previous issues, but I haven't quite found the solution to my case. I've tried erasing the csdevkit folder in my Temp, changing dotnet.server.trace, and unchecking dotnet.server.waitfordebugger. None of them have worked yet. Is there a solution for this?

#Environment

  • OS: Windows 11 64-bit
  • VS Code Version: 1.9
  • C# Dev Kit Extension Version: v1.11.14
  • .NET SDK Version: 8.0.110

Steps to reproduce

Open VS Code.
Install the C# Dev Kit and .NET SDK.
Open a C# file and observe the error output.

Expected behavior

Editor to show errors in C# codes
The language server should start without throwing an exception and enable IntelliSense and other C# features.

Actual behavior

No errors are shown every time even with obvious ones.

Additional context

I've tried reinstalling the C# extension and .NET SDK, running VS Code as administrator, and disabling telemetry. None of these steps resolved the issue.
