def handle( # type: ignore[override]
self,
a: int,
b: str,
c: str,

**options: Any,
) -> None:
pass
Causes an internal error:

I tried to reduce the example, but it cutting it down to a minimal reproducer turned out to be complicated, after some changes it no longer appears. Let me know if you need a better reproducer and I'll see what I can do.
