Unable to discover NUnit tests

[miksch123]

Since version 7.7 I no longer can see the list of tests in the testing area of VSCode.
Reverting to 7.6 does not seem to have this issue. I also tried different ways of setting the project path in settings.json or the extension settings.

1. Dotnet sdk version: dotnet core SDK 3.1.417
2. Unit test framework: NUnit 3.13.2, NUnit3TestAdapter 4.2.1

I also am running my project in a VMWare VM.
