Unexpected error opening catalog in Lightroom Classic 10.4 on M1 Mac running macOS 11.5.2

I've gotten the unexpected error opening catalog error on a Mac M1. It seems to affect several versions back of my backup catalogs as well (as suggested to try in other posts.)

When I click "Try Again" the catalog opens.

I imported this catalog into a new catalog, with no errors. But after saving, I reopen the program and get the unexpected error again. I'd really like to avoid having to somehow recreate my catalog. Any suggestions are welcome.

Version:LR Classic 10.4

Mac OS: 11.5.2 on Mac Mini M1

Try unzipping a recent backup and placing the unzipped catalog in a brand new empty folder and then opening the catalog. If that doesn't work, try unzipping a recent backup again (not the same unzipped file that you used in the first sentence) and place it on a different hard disk, and then opening the catalog.

I tried a backup on internal drive - error.

I tried a backup on an external drive - no error 1st run. Saved and reopened - error.

Thoughts?

Hardware malfunction somewhere. Could be hard disk or memory chips or even the motherboard. Run diagnostics.

Hi,

We're sorry about the trouble with Lightroom Classic due to the unexpected error while opening catalogs. Are the catalogs & backups stored on an external drive? If yes, try moving the catalog to the Macs local storage to check if that helps.

Please ensure that Lightroom Classic has the necessary permissions on your Mac by following the steps mentioned below:

1. Go to the System Preferences for your Mac, then Security and Privacy, then select the Privacy tab.

2. Then select Accessibility from the list to the left & check if Lightroom Classic is added to the list with a check mark in front of it.

3. If Lightroom Classic is not a part of the list, please add it by unlocking the window first using the lock at the bottom left, then clicking the + icon & navigating to the Applications folder.

4. Also, grant permissions to Lightroom Classic under Full disk access located in the same list as Accessibility.

5. Once done, restart the Mac & check if it helps.

Let us know if it helps!

Regards,

Nikunj

I checked. LRC was not on the Accessibility list but was in the Full Disk Access list. I followed your instructions, no change. Still unexpected error, try again still allows opening.

This was on the main, internal hard disk to begin with.

Thanks for your help!
