I don't have Maya 2020 installed on my machine so I can't test this myself but you could try adding some code to the top of the script to import the "future" module which will allow some python3 functionality to be used in python2.

If that doesn't work you modify the code based on what is not working (fixing syntax differences and stuff).

Or you could upgrade to windows 2022 where python 3 is standard.

When you run the code do you get errors? If so you can use info like this: https://portingguide.readthedocs.io/en/latest/ to help you make the changes necessary to work in Python3.

If you're not getting errors then you'll need to manually check through the code for any syntax whose behavior would have changed between py2 and py3 (you can refer to that same link to know what to look for).

When you try to run the code, are you getting errors? or are you getting the incorrect result?

So the area around line 66 looks like this

try: #python2 reload except: #python3 from importlib import reload

I don't have 2.7 installed on my computer so unfortunately I cannot test it myself, but you should be able to remove that section completely since reload is a standard part of python 2.
