Regression?

yes, preview5 works fine

Other information

I verified issue on main (7b0cdaf) it still there.
I can't create a small repro but I have 100% repro in our tests.

I couldn't figure out the best area label to add to this issue. If you have write-permissions please help me learn by adding exactly one area label.

        static int Main(string[] args)
        {
            // Test that the a generic using a variant of the curiously recurring pattern involving an interface can be loaded.
            _o = typeof(CuriouslyRecurringThroughInterface<int>);
            return 100;
        }
    }
}

This is caused by PR #54588. Fortunately #54941 is unrelated and there are no race conditions to deal with.

@davidwrighton I verified the fix from PR in our tests. Looks good, no hang anymore.
