LR Classic not opening. Shuts down Immediately

[Victor_W]

LR Classic stopped opening. I have repaired Creative Cloud, Uninstalled and reinstalled all Adobe applications, I have verified the permissions, and ran malware cleaner prior to all of these. LR Classic starts to open and then shuts down before it if fully open. It was working fine and the next day it was not. This is on a M1 Macbook Pro running Samona 14.2.1 . Any help would be greatly appreciated. I am out of commission until this is resolved. Thanks

If you log onto your computer using a different account, what happens? If your account is an admin account, then you would need to create a new admin account and test with that account.

Hve you perchance tried resetting the LRC preferences?

1. Start Lightroom Classic while holding the Shift + Option (macOS) or Shift + Alt keys (Windows). 

A dialog box asks if you want to Reset Preferences. 

3. Click Yes.
