Btrfs snapshots not always work tho), i tell this story for *th time on lemmy but my fedora 38 btrfs broke completely from update to 39 and when i tried revert to 38 with help of btrfs snapshots, what came out is weird mix of 38 and 39 and when i reverted again, my whole ssd on which fedora btrfs was installed, this ssd locked completely, on hardware level, even though it was brand new, 2 weeks of usage by me, i fortunately repaired ssd myself and flashed lmde6 on it, but avoided btrfs and fedora after that
