Crash with `set[]` annotations

[TeamSpen210]

I'm getting plugin exceptions when opening certain Python modules, in particular this one. Commenting out the highlighted line (a global var: set[SomeClass] = set() assignment) and restarting doesn't produce an error.

Original error

In attempting to produce a simpler example, I found also this code gives a slightly different `ClassCastException`:

some_global: set[str] = set()
second = some_global.add('45')
