Library links with photos broken

[Dirk el bondadoso]

I use LRCC 11.2 on a iMac - MacOS Monterey12.2.1. I pay by month for LRCC and PS. Yesterday when I opened LRCC libray none of the folders or photos were linked anymore with the folders or photos on my external HD (Lacie Raid 12TB) (HD where the photos always are located). When I tried to reconnect them with a right click the folder or the photos disappeared from the library. The photos and folders still are on the HDD. Restarting LRCC did not changed anything. I temporaly moved the catalog and replaced it by a backup catalog but no result.

What is the solution here?

Has the external drive been offline?

No the external drive has not been offline. The only thing that I can think of is that I made a few days ago a backup with Intego Backup Manager Pro into an other external HDD as I use to do every week. I never had a problem doing so.

Should I uninstall lightroom CC and install again?

Uninstall/re-install never solves catalog problems. Total waste of time here.

They did not disappear. Lightroom Classic now shows them in a different drive and/or different folder. Why? Because you have told Lightroom Classic to do so when you reconnected them. Do a search, using the Filter Bar in Lightroom Classic, for one of these photos. You will find them,
