Not quite, it’s that you’re using a third party kernel module with a non-LTS kernel. Just don’t do this.
That, or disable this: https://git.sr.ht/~mapper/nixos-fixable/tree/master/item/configuration.nix#L231
If I had to guess, that module might also be the culprit as far as your stability goes, but the framework forum is likely better equipped to debug that.
