I've had multiple problems with the Elipsa database since I have it, as I've explained in detail elsewhere

I had hoped now the DB is more or less stabilized, it would stop, but no! Since I saved it yesterday evening, it should be more or less painless, but I'd like to understand.
So here is this morning's error message

Spoiler:

CorruptError: database disk image is malformed

And here the result of Kobo Utilities' DB check:

Furthermore I can't open any of the PDFs I was happily reading on Elipsa, while the kepubs work fine. I suppose it is linked with the DB problems.

Can somebody explain what might be happening, so I could understand and prevent it recurring again and again?
