So I have a desktop with Ubuntu, and my graphics card is a GeForce GTX 1060. I switched from Ubuntu 20.04 to 22.04 about a week ago, and haven’t had any problems at all - until yesterday. It was then that my computer froze, seemingly randomly.
Nothing was responding for like 10 minutes, so I turned it off by holding down the power button, and then turned it back on again.
Upon booting up though, I noticed that everything was significantly slower. Looking at Additional Drivers revealed that the list of drivers was completely gone, along with any mention of the GPU.
I tried updating the drivers with ubuntu-drivers autoinstall, but to no avail - it just says that all the drivers are up-to-date.
Running sudo lshw -C display didn’t seem to detect the nvidia card either. Instead it listed a UHD Graphics 630, which I guess is the... backup graphics card or something?
At this point I’m not sure what to do. Has anyone here dealt with this before? What might cause Ubuntu to forget about the graphics card, and is there any way to fix it?
UPDATE:
I just booted from a live usb with Ubuntu 20.04, which seemed to recognize the graphics card just fine. So it's not a hardware issue, thankfully. I guess it's something specific to my current installation?
I'd really rather not reinstall the OS though, if I have any choice. Also I have no idea if the bug is version-specific, so it's possible I might encounter it again in 20.04 anyway. Which would mean I'd reinstalled for nothing.

Just booted again from the same live usb as before, and this time the problem did not go away. No nvidia card to be found, and no drivers in Additional Drivers. The only other issue I encountered was that the disc-check at the beginning ended with "found 23 errors on your system", before proceeding to the installation menu. Maybe it's correlated?
But anyway, now I'm back to having exactly 0 solutions. I have no idea how to proceed. Any more help would be greatly appreciated.
UPDATE 3:
