Lost catalogue

Hi, LR classic can no longer locate my catalogue after updating the software on my MacBook Air yesterday (to OS Monterey version 12.3.1).

Does anyone know how I can fix this please?

First, do this: Go to MacOS 'System Settings - Security & Privacy' and add Lightroom Classic to "Full Disk Access". Click on the lock icon to unlock the settings, then click on the plus icon to add Lightroom Classic if it isn't already listed. If it is listed, then just enable the checkbox.

Then, if Lightroom can still not find its catalog, find it yourself manually. Double click on the catalog file to launch Lightroom. You only should have to do this once. From now on Lightroom knows the location of the catalog again.

Hurrah!  Thanks so much that has solved the problem.
