Typing.get_type_hints failed with

Hey guys,
I’m getting an error that looks like:

typing.get_type_hints failed with: WM_OT_project
Traceback (most recent call last):
  File "C:\Program Files\Blender Foundation\Blender 2.93\2.93\python\lib\typing.py", line 1408, in get_type_hints
    base_globals = sys.modules[base.__module__].__dict__
KeyError: 'Workbench Render'

Honestly, it looks like my script still works correctly, but I’d like to fix this error if I’m doing something wrong. Unfortunately, the setup is a bit involved (I’m creating Operators on the fly and assigning their execute function to be what it loads from external scripts - and this external script in particular is creating its own Operator so I can create a pop-up dialog), so I can’t easily post code here, but does anyone recognize what might be going on right off the bat?

@WCN figured out that it is a bug in python itself, reported it upstream, and python devs want to get a fix in for python 3.10 by the final July 10th Beta
