Lightroom Classic Not Working

[MDPhotographer]

Hello,

I have updated my Mac software (15.3.1) and Lightroom Classic (14.2), NOT WORKING. It was working last night when I exited and backed up my catalog, but not today. It gets past the preferences stage, goes automatically to recent imports, then stops functioning (just spinning wheel).  I have tried uninstalling and re-installing to no avail. Please help.

Good morning,
this week I had a similar problem after mac update to 15.3 and LRC update to 14.2. I was no longer shown any images to import - neither from the SD card nor from my hd. After contacting support chat I received a downgrade link for LRC 14.0 from Adobe Support; after uninstalling with cache and cookies and re-installing, everything is fine again 😅.
Good luck, Birgit

It's recommended to backup your preferences before you reset the preferences to the default settings:
