An internal error has occurred. (fatal SQLite Corruption)

The following error (in brackets below) has happened.   My LR file loads but the error comes up when I try to copy setting from one image and then hit "paste" to another. - then it crashes.

It's probably caused because I had removed the original LR folder and copied to external - as well as moving all the source RAW files to external - all due to a system wide backup - headed for a clean install after a migration to a new Mac Studio M2 (worked but a bit buggy)  Sonoma 13.1.2 - LR Classic 13.1

I moved everything back in place on the internal SSD and tried again (using the copies) but it didn't seem to help.

Luckily rebuilding everything with a new catalog is pretty easy - but it would be nice to know what happened - and hopefully be assured that my copies of other LR catalogs (all now moved to externals) are not at risk.
