Are you confident that the issue is a new issue? Unfortunately as best I can tell, the corruption can occur and then will still appear on a fixed system if it's reading corruption created in the past that unfortunately scrub doesn't seem to detect.
I've still had no re-occurance here after a few weeks on hirsute with 2.0.2-1ubuntu5 (which includes the https://github.com/openzfs/zfs/issues/11474 fix) - but from a fresh install.
