This supports my initial reply. This was an f2fs bug in a bleeding edge kernel released only seven days earlier. The thread suggests perfectly reasonable mitigations, especially for an arch user: use the lts kernel or downgrade to 6.8.9.

If you're not familiar with linux and/or don't want to deal with trivial issues periodically, don't hang out at the bleeding edge. There are plenty of boring and/or beginner friendly choices out there.

I'm not saying linux is perfect, but your conclusions in this instance appear to be uninformed rather than supported by the facts.
