I took a look at it and changed it for me, I don't know if that could go through as a possible fix.

if target_id is None we just return None just like AuditLogAction._convert_target_user

[Error44s]

In this case it is then one of the two or simply copy the one from AuditLogAction._convert_target_user ig.

def _convert_target_message(self, target_id: Optional[int]) -> Union[Member, User, Object, None]:
    if target_id is None:
        return None  # Explicitly handle None
    return self._get_member(target_id) or Object(id=target_id, type=Member)

or

def _convert_target_message(self, target_id: Optional[int]) -> Union[Member, User, Object, None]:
    return None if target_id is None else self._get_member(target_id) or Object(id=target_id, type=Member)
