Description

Admin checks include several calls to issubclass without a try/catch, allowing a TypeError to escape if the user provides a value that isn't a class for whatever is being checked. This seems like a sane-enough edge case to ensure the user gets a useful check failed message rather than an uncaught exception. Providing a PR that uses a helper function that catches the TypeError and returns False instead so that the half-dozen checks that use issubclass have minimal code change.
