Lightroom Classic suddenly stopped launching on Mac

[k k daga]

My lightroom classic has suddenly stopped launching on Mac (M1). I have uninstalled and re-installed it but problem remains. Screenshot attached.

Try 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.

If that does not help, then reset the preferences: https://www.lightroomqueen.com/how-do-i-reset-lightrooms-preferences/

Your screenshot indicates that LrC is stuck at reading the preferebce file. Cabn indicate that the preference file is corrupted.

The preference file can get corrupted leading to buggy behavior. A corrupt preference file will survive uninstalls, updates, and upgrades. By renaming or moving or deleting the preference file you create a situation where LrC will recreate a fresh new one upon startup of LrC. Be aware various settings will revert to defaults.

Did you check the permissions like I suggested?

Hi,
Did that but it didn't work only with that. I
uninstalled>restarted>Reinstalled Lightroom and now it worked but with my
backed up LRCatalogue. With the current catalogue it was giving the
same issue. Looks like the current catalogue got corrupted.
Thanks for support
