Failed integrity Cannot back up
I have had this several times and thought I'd solved it. I see the message
"we're sorry, the catalog ... failed the requested integrity check and cannot be backed up"
This is on the latest release and I last time it happened had to revert to an older version of LR (which worked fine) and re-do the upgrade. Yesterday all was fine on opening and upon closing I got the message again.
Why does this keep happening?
My library is on an external Samsung SSD T5 and is quite big - but as I say all was fine before updating to latest LR version 12.1
Thank you,
