Lightroom crashes soon after starting up. I've already disabled the Graphics Processor to no avail.
I can prevent crashes by turning off the Creative Clound which makes me suspect that the syncing (with mobile) is what is causing the problem.

Please close all the Adobe application and uninstall the Creative Cloud Desktop app.
Restart your machine and reinstall it and check if that helps.
Let us know if that helps.
Unfortunately, I tried the procedure twice to no avail. Removed Creative Cloud and Lightroom, reinstalled everything and started Lightroom. It stays up for about 30 seconds and then crashes.
I was ready to sign up but it is critical that the desktop app works. Any assistance will be highly appreciated.
