Was taking a second look since the first one was on the phone and it's not so easy to look at the log, and I did miss this line:
Jun 30 17:43:58 Kaokulk kernel: BTRFS error (device nvme0n1p1): incorrect extent count for 19382927360; counted 1535, expected 1532
Fs is not going read-only, so this might not be the problem, but it is a problem, first time I remember seeing this error, so not sure how serious it is, you should make sure backups are up to date and attempt to repair the filesystem, or backup and re-format the pool, there's also this which I saw before:
Jun 30 17:43:51 Kaokulk kernel: BTRFS info (device nvme0n1p1): bdev /dev/nvme0n1p1 errs: wr 0, rd 0, flush 0, corrupt 4, gen 0
Jun 30 17:43:51 Kaokulk kernel: BTRFS info (device nvme0n1p1): bdev /dev/nvme1n1p1 errs: wr 0, rd 0, flush 0, corrupt 2, gen 0
Some data corruption was found at some time earlier, it might be from a while ago, still this is usually a sign of bad RAM or other hardware issue, if you don't re-format the pool you should reset the stats ad keep monitoring.
