Lightroom Classic doesn't start up anymore

[Paul247939458bje]

Hello everyone, 

After deleting some files in my Mac Book Pro Catalina 10.15.7 (13' 2012) this morning in order to accelerate it, I cannot open Lightroom Classic anymore. 

I was on the 11.3.1 version. The logo appears on the bottom bar but it disappears few seconds after. 

I did the uptade to the 11.4 version, no change. I did the downdate to the 11.3 version, no change. I tried to uninstall, reinstall Lightroom, no change. Uninstall/Reinstall Adobe Creative Cloud, no change...

I opened it up in safe mode to reinitilize the preferences, and rename the SLStore and SLCache files with "old" but I still have this problem...

Do you have any recommendations ? 

Thank you for your time.

Paul

It seems that the problem come from the update of Mac OS Catalina 10.15.7 that I did yesterday..

Do you have any other solution than the downgrade to Mojave ?
