Lightroom Classic V12 on Mac OS Monterey 12.6 opens and then closes

[dparke01]

Today went to log-in to Lightroom to work on photos. Running Lightroom V12 on a 
iMAC Pro (Monterey V12.6) and the app fully opens and then closes. Did a First Aid on the computer (all Volumes) restarted the computer and same thing happened. Subsequently uninstalled Lightroom and then re-installed the app. Same results. Please HELP.

1. Did v12 previously work?

2. The last time you used it, did it close properly? Or did it crash? Or did you force quit?
