Yes, sorry, I can kind of see the issue happening with kernel 5.8.0-59.66~20.04.1-generic in prevboot3.txt. In case something related to the login screen has crashed, please look in /var/crash and tell us what you find.
It also appears you still don't have the Nvidia driver installed so please try to install that again with:
sudo apt install nvidia-driver-430
because the Nvidia website seems to recommend stable driver version 430 for your card, or 465 if you need newer features.
Finally, your wifi driver 'rtw_8822be' (or wifi card) appears to be broken and the kernel is flooding the log with errors. I'm not sure if that's related to the main bug here though.
