Seems like python 3.10 disallows these types of conversions. We've run into these issues with Qt-based plugins we ship with PyMOL (e.g. Lighting Settings) after updating to 3.10. I haven't tested yet with the scripts here yet though, but I wouldn't be surprised if many of them here started to stop working for the same reason.
Example from another plugin's issue tracker:
vanderkamp/enlighten2-pymol#1
