I could be wrong, but maybe any answer is more comforting than no answer?
As DNSB said, Kobo changed some options in the database starting with the 3.20.x firmware. I don't know if they changed the version of the SQLite library they used at the same time. It's more likely a corruption would happen when migrating to either the 4.1 or 4.2 firmware. In one of those, they changed how some data was stored and, from memory, the migration updated all of that. That would affect anyone coming from earlier firmware to a one of those or later. The main issue with this would be the amount of data updated. For anyone with a lot of books, and had done a lot of reading, then there would have been a lot of updates. The chance of something going wrong, increases with the number of changes needed.
