Python 3.10 TypeError: issubclass() arg 1 must be a class #1903
Description
Initial Checks
- I have read and followed the docs and still think this is a bug
Description
TypeError for issubclass in python 3.10. Works in python 3.11.
I think it is due to usage of issubclass that is missed out in the following.
