An internal error has occurred. (fatal SQLite Corruption)

[KE_DP]

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.

What MACOS version?

What LrC version?

Where do you keep the catalog?

I've edited/added the additional info - Sonoma 13.1.2 - LR Classic 13.1

*Where* the catalog is - user/photography clients folder/client name folder/client name LR folder

This is where it was originally - then copied to (redundant) externals and erased from internal.  When run from the external it had the same failure - so I tried putting it back in the original place and it didn't help correct the copy/paste crash - the lrcat file does open though.
