Kubuntu fails to boot after updates (discuss.tchncs.de)

Hey there, I could use a little help.
I'm running Kubuntu 24.10 (the non-LTS variant) and after some system updates through KDE's Discovery, I'm unable to boot.

First off, some specs:
Kernel: 6.11.0-14-generic
GPU: GTX 1080 w/ proprietary drivers, version ~~560~~ 550 stable

I was first greeted with these lines:
[ TIME ] Timed out waiting for device dev-disk-by/x2duuid-[...].device
[DEPEND] Dependency failed for mnt-games.mount

This is not the first time this happened, so I went into recovery mode, opened /etc/fstab to comment out the device-specific line, saved, and rebooted.

The error disappeared, however the system still won't boot and I'm left with these entries visible on screen (abbreviated for clarity):

[ OK ] Started cups.service
[ OK ] Reached target printer.target
[ OK ] Started ipp-usb.service
[ OK ] Finished NetworkManager-wait-online.service
[ OK ] Reached target network-online.target
[ OK ] Started update-notifier-download.timer
[ OK ] Started update-notifier.motd.timer
[ OK ] Reached target timers.target
[ OK ] Started cups-browsed.service
Starting kerneloops.service
[ OK ] Started kerneloops.service
[ OK ] Reached target multi-user.target\
Starting power-profiles-daemon.service
[ OK ] Started power-profiles-daemon.service
[ OK ] Reached target graphical.target
Starting systemd-update-utmp-runlevel.service
[ OK ] Finished Starting systemd-update-utmp-runlevel.service

...and then nothing.

~~I need to leave, I'll fix the formatting and provide further information as soon as I'm back at my desk.~~

UPDATE:

I was able to recover my system by re-installing the NVIDIA drivers through, in my case, sudo apt install nvidia-driver-550 since the kernel log indicated a version mismatch, presumably due to the Discover updates. Something's still janky with the drivers as I experience massive lag and a ghosting cursor, but I'll figure that out.

I'd really appreciate tips on how to prevent this in the future.

Do you have time shift setup? If this happens again you can put the USB in and chroot into the system the run time shift to take you back to a version of your system that worked.

It's on my to-do list, but I haven't gotten around to it yet.

Its a very quick setup. Probably takes ~1min
