Psychopy on Big Sur on mac

Eek. So I have some people doing a longitudinal training study (which is covering a significant period of time) that I created in PsychoPy v1.90.2. Someone’s just updated their OS to Big Sur and they’re now receiving the following error message:

Traceback (most recent call last):

raise ImportError(“Can’t find framework %s.” % path)
ImportError: Can’t find framework /System/Library/Frameworks/OpenGL.framework.

As mentioned in the thread above, the issue seems to be with Pyglet and OpenGL. Can anyone recommend a potential way to fix this in such an old version of PsychoPy?

Help much appreciated!
