Rider Debug stuck on pending

I have some tests within my application using .net core 3.1, and I can run, them without any problems.

However, when trying to debug the tests rider gets stuck endlessly pending in the Unit Tests tab.

What can I do to fix this and properly debug my tests?

here is a log of the run, you can see the big gap between the start of the run and aborting the run:
