Lightroom constantly crashing and unusable

Report · May 13, 2020

Hello, as the title says, whenever I use Lightroom classic it just crashes and I'm unable to edit even one photo, I have had this issue for over 12 months and tech support don't have a clue, they blame it on catalogues which it clearly isn't, they just keep on throwing free months at me to keep me happy but now I'm fed up! This only happens on LR classic, LRcc works fine as does photoshop with no issues at all, Anyone have any info or help? I have left part of the error log below

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.

Go to Lightroom > Preferences > Performance tab > Uncheck "Use Graphics Processor" > Restart Lightroom.

If Lightroom doesn't start correctly the please see "Solution 2" in the document behind the second link.

Another step is to try to reset the Lightroom preferences.

Thanks for the reply, its has been turned off since I first spoke to tech support 12 months ago, and whenever I speak to new tech members support they always say the same thing, the funny thing is though sometimes LR doesn't open long enough before it crashes to allow to even get to the preferences menu!
