A new problem?

I tend to add Tidal albums to my library, because of the nice navigation, "other albums by this artist" etc. But I got some albums I didn't want, some Tidal favorites I already owned, some Tidal I subsequently bought, some Tidal that wouldn't play because Tidal says "the publisher disallows" (so why include them?).

Anyway, I deleted them. Consistently crashes the core. Both from Control:PC and Control:10.

It recovers in a minute, and the user interface shows "loading your library".
