This was CR from earlier today.
But since then I'm only getting them when running
calibre-debug. Otherwise it just quits instantly without generating one.
I did experiment with moving metadata.db but it didn't help.
I ran First Aid on the SSD volumes and it didn't report any problems.
I tried installing new calibre.app (after renaming original calibre.app), problem is still happening.
Maybe a system file is out of whack? I'll try reinstalling macOS.
