LrC immediately exits splash screen
Summary
After starting LrC I get the splash screen and immediate exit from LR, sometimes I get the spinning ball for a few seconds and then exit.
Details
I used LrC earlier in the day to copy a number of photos from a Catalog folder to a Collection folder. I closed LrC and selected the Backup option and no errors were indicated. Later when starting LrC I get the behavior above.
System Environment
I'm using an iMac desktop running MacOS Ventura 13.5.1 and LrC 12.5. My photos are on a network drive and my Catalog is on my local disk and Dropbox with off-line access enabled (i.e both local and in the cloud). I have had this configuration for a number of years without problems.
Additionally, I have a MacPro laptop running LrC and pointed at the same photos and Catalog as the iMac. The laptop is behaving correctly, i.e. I can start-up LrC.
Things I have tried (to no avail)
- Rebooted the iMac
- Signed out of Creative Cloud and then back in
- Uninstalled LrC and reinstalled it from CC
- Checked that lr.lock file is not present when starting from the iMac
- Set the permissions on the suggested Library files to read-write for everyone, they were already read-write for myself
- Started LrC with (shift)+(option), I get the screen to reset Preferences, the splash screen and then exit
I've run out of ideas, any suggestions would be welcomed.
