I am convinced that calibre corrupted the database on my brand new forma at least 3x. Both times I restored the database from the kobo utilities backup and everything was ok. Once the forma reset itself and logged me out. I am very sure I ejected correctly every time, and at least one of the times I hadn't done anything on the kobo except import books between when the database was OK and when it was corrupted.
Whatever the problem was, it went away when I upgraded from 4.x to 5.2 and then upgraded all my plugins. Sorry, I didn't try to debug it.
It may have been a race condition between calibre modifying the sqlite database and a plugin modifying it.
