If the code is hanging it is probably because it is waiting for Main to finish. That is not a unit test anyway, what are you testing?

Testing main method is a bad idea.
First of all, there are no direct outputs to verify because main returns void (or Task)
Secondly, if your goal is to verify the side effect method produces, you cannot mock your dependencies. Which in turn makes your test more of an integration test.
Extract logic you want to test into a class and test it.

Solution 2

You cannot catch any exception in an async void method anyway.
Avoid async void methods[^]
