From what I've seen in the logs (posted earlier in this thread), my hunch is that the crash/reboot is caused by an attempt by the Core to delete files that exist for a regular local album and perhaps a Rhapsody album, but not a Tidal album.

I'm not in a position to test this at the moment, but it would be interesting to try to manually delete one of the .fse or other required files for a local album and then attempt to delete this album via Control:Mac/PC.
