SQLITE Issue Preventing Music Library Updating

UPDATE:
Thanks to the advice at https://forums.plex.tv/t/how-do-i-revert-back-to-previous-plex-media-server/718136/2 , I’ve reverted back to v. 1.22.3.4392

That’s working fine, which supports the idea that something’s a bit funky in the latest version, since that is all that has changed.
