There was a problem hiding this comment.
python/typeshed#14786 changed the signature of copy.replace from
_SR = TypeVar("_SR", bound=_SupportsReplace)
def replace(obj: _SR, /, **changes: Any) -> _SR: ...to
def replace(obj: _SupportsReplace[_RT_co], /, **changes: Any) -> _RT_co: ...which our generics solver does not support yet 😢.
I don't think it's important enough to implement a workaround for, though.
