Can't run "dotnet build" or "dotnet restore" in Gitpod

[RoboMico]

Bug description

I'm a .NET developer using Gitpod and recently it seems that I can't use dotnet build and dotnet restore in Gitpod workspace. I always get the same exception:

MSBUILD : error MSB1025: An internal failure occurred while running MSBuild.

Last time I used Gitpod was about 4 months ago and dotnet build runs well then. There is also a post about the similar error in the community. Is the error caused by .NET SDK or Gitpod itself?

Steps to reproduce

1. Open the example repo in Gitpod: https://gitpod.io/#https://github.com/MineCommanderCN/gitpod-bugged-dotnet-cli-example
2. Try dotnet build and dotnet restore;
3. Both get the exception above.

This situation only happens after building a multi-projects solution. However, it doesn't mean that single project works well. Just replace the example repo with your offical dotnet example repo, and a new error appears:

Microsoft (R) Build Engine version 16.9.0+57a23d249 for .NET

  Determining projects to restore...
  All projects are up-to-date for restore.

Build FAILED.

Both two errors have nothing to do with the VSCode extensions. I tried to uninstall it and it didn't work. By the way, it is still fine to run restore command through the extension, but I didn't try building.

Expected behavior

No response

Example repository

Multi-projects solution: https://github.com/MineCommanderCN/gitpod-bugged-dotnet-cli-example
Single project: https://github.com/gitpod-io/template-dotnet-core-cli-csharp

Anything else?

Maybe related post about this error: https://community.gitpod.io/t/cannot-run-dotnet-tool-restore/4388
It also points to #5064.

Hey! Thanks for flagging this, #5064 also covers this I believe and this community post.

Please follow #5064 for updates!
