Updated to Lightroom Classic 11.0.1 on iMac and now Lightroom won't start at all. I have tried restarting computer, uninstalling and reinstalling LR, going back to version 10.4 and it still will not load. When I launch it from the dock or from CC, the icon bounces like it is launching, but then nothing happens. When I click on the icon, it says the program is not responding, and I have to force quit, but there is not a window or splash screen or anything. Help!
The first thing that you should try is to switch off the GPU support from the Lightroom preferences and check if that helps to fix the issue. Please see "Solution 2" in the document behind the second link.
I have the very same issue with my Windows 10, 11.00 did start but was buggy with the cataologue. Took the upgrade to 11.01. It ran once but after clsoing down the app and comming back to it and attemtping to start it...it no longer runs. It shows runing as a backgournd task. This is VERY VERY disturbing. FIX it .. FIX it now !
