Looks like my third Linux installation - 2 Ubuntu after a month or two of normal work, and this time Mint, also after a couple months of work - got a problem. I did not install anything on it to justify change in behavior. It was as usually running multi-core apps in background. I am very conservative with any new installations, but this did not help.
In my case Timeshift failed to work from the start because it also chose to save snapshots in small /boot partition of other Linux OS, always failed and did not report what the problem is.
Approximately with the same diagnosis got corrupted my Ubuntu - it initially lost sound settings with no reason at all and did not got back no matter what the cure was, then stutter in apps started larger and larger. Stutter feels like your wireless mouse almost lost the battery - you try to move window and need to do that few times because mouse permanently loses the grip. Or you need to click several times on x in the right upper corner of window of any app to close it, you click OK and nothing happens. You try to highlight the text with the mouse and mostly fail or highlight only part of text...
Worst of all mpirun stopped working with the error

Mint apps under WINE work also OK like nothing happened, looks like Linux gamers desperately wanted Windows to work flawlessly no matter what
Is this possible that this is caused by the fact that i always installed Linux on the NVMe drives and by some reason some places of it got excessive wear?
I noticed that one of my older NVMe drives (all are WD 850x) copying files 10x slower than newer ones. Typical usage of these drives is pretty large, a couple TB per week. All manufacturers claim a petabyte of endurance for lifetime but who believes the claims when most of users will never reach 1% of that hence you can claim anything you want even infinite life
By the way i only ones needed to repair Windows 20 years ago and never needed to repair Android despite of gazillion of installs and tons apps there
