In the process of troubleshooting Maya 2020 (Windows 10) instantly crashing upon loading, I may have stumbled on a possible solution to your problem. I didn't know it at the the time, but the Unreal Livelink Plugin was crashing Maya 2020 but not 2022 (it works correctly in 2022). Without uninstalling the plugin (which unfortunately loads automatically even if it's disabled in the plugin manager), I was able to stop the crashing with the information from this link:
Link from support.foundry.com
"As a workaround, you can set the following environment variable to correct the issue:
OPENSSL_ia32cap=~0x200000200000000
You can do this by accessing Control Panel > System > Advanced System Settings > Environment Variables… It’s possible that you may have to restart the machine after adding the environment variable for it to take effect."
There's a screenshot there that shows where in the Environment Variables Window (System variables) to input the variable name (OPENSSL_ia32cap) and the value (0x200000200000000). In my case it immediately took effect after adding the value and pressing OK.
Maya 2020 stopped crashing and it may allow the Unreal LiveLink Plugin to run. I can't confirm if it will however, as I haven't re-installed the plugin while troubleshooting.
A 0xc0000005 exception code for maya 2020.exe that I spotted on the Event Viewer --> Application log led me to that link somehow.
Hope this helps. 🙂
