Ah, I see the problem. The code currently assumes that when the main interpreter is finalized, that no other interpreters are still around. I'll have to fix that.

Isn't it a duplicate of #113433?

It's definitely closely related (and the fix for gh-113433 will fix it), but it is a slightly different problem.
