Looks like BTRFS corruption, your diagnostics would provide much more information (for example on what drive allocation). Go to Tools / Diagnostics and attach the zip file to your next post.

Cache filesystem is corrupt, log shows previous write errors to one of the devices:

Best bet is to backup and restore the pool, also see here for better pool monitoring.
