I have stripped all code out of the project that i could manage, and it still yields the same error! New folder.zip

Here one of both is redundant and may slow down… also using the nuget cache makes it much slower in general

      "referencePaths": [
        "%USERPROFILE%/.nuget/packages"
      ],
      "useNuGetCache": true
