File system goes read-only on NVMe SSD seemingly at random

I am currently running a somewhat fresh Kubuntu 22.04 install on a relatively new M.2 NVMe drive. However, I have a problem where my computer drive (I think) turns read only, causing the system to sort of crash. When I first installed the system, this would happen very frequently until I applied the

=off

fix to the /etc/default/grub file:

="quiet splash pcie_aspm=off"

. This made it happen less frequently. This issue happens on all the previous systems I've tried to install on this drive, with most of the same symptoms, i.e. some icons disappearing, apps breaking, chromium tabs displaying "aw snap," and in particular, libreoffice gives a "filesystem read only" error when trying to save. One thing different from similar errors though, is that when I reboot the computer manually (holding power button) it goes back to normal for a while, while some seem to have problems booting afterwards. Then it happens again some time later. I can provide more details if needed, e.g. hardware, syslog entries, etc. Does anyone have a permanent solution to this? Not a computer whiz, but I do know some.
