I didn't want to fill the question with a bunch of useless STATUS realtek-rtl8814au, 5.8.5.1~git20210331.bdf80b5, 5.4.0-100-generic, x86_64: installed Let me know what logs or system info would be helpful to diagnose further.
#UBUNTU CHECK GRAPHICS DRIVER NVIDIA DRIVERS#
When I look at the additional drivers through the Gui, I can see all of the Nvidia drivers listed, but can not select them as it says 'this device is using a manually-installed driver' I've been searching a lot of forums and trying to follow the recommended advice, but nothing seems to be helping to resolve the issue.

I did a apt uninstall -purge for everything Nvidia, rebooted and was able to login to the Gui normally, but now if I try to reinstall (even a newer set of Nvidia drivers), when I reboot, the login prompt is missing from the Gui again. I used Ctrl+Alt+F5 to get to a terminal and saw a message that there were 24 updates that could not be installed automatically so I went and checked the /var/log/unattended-upgrades and saw that they were all Nvidia related. I'm running Ubuntu 20.04 and did the latest round of updates, and once completed I was getting to the login screen but it was just blank.
