Using Visual studio code :

The issue was simply due to the length of the path of the csporj file, the path has exceeded 256 characters. I justed renamed the csproj files and it worked fine.

Using Visual studio :

If you use viusal studio for tests, this will not work even if you update the longpath property in the registery database as it is doing its own validation
