It did it first on my PC, then it happened again on my laptop. That is when I investigated the cause and found out BTRFS corrupts on hard shutdowns/failures. Beyond maybe a UPS battery backup that will allow you to MAYBE have some extra time to shut down properly before the battery fails, no. I would highly recommend backing up your data and reformatting to ext4.
I have several (at least 5) BTRFS filesystems, on SSDs and HDDs of varying speeds, with somewhat longer cache writeback and commit times, AND some wire problems that trip my apartment breakers once or twice every month;
I’ve been using BTRFS for about a year and a half, and at worst I suffered loss of newer data.
The BTRFS users are relying on backup systems, so make sure you have extensive backups as power failures can happen at any moment, etc. For me personally, a files system that so easily corrupts files, especially when power failures occur frequently, is not what I want. I will stick with ext4, a log file system, which is more stable.

BTRFS lets me backup my stuff more conveniently too, although it does start throwing a tantrum if you run out of space due to COW…
