I have big problem with the new update of Lightroom Classic CC 7.3 and it is crashing a lot. It has crashed when I used the Profiles browser and also when I used ordinary presets. I´m not doing anything else with LR but with this new version seems very unstable, the 7.2 was very stable. I have checked so I dont have GPU acceleration on plus I have updated with the latest graphicscard drivers.
One other problem is with the converted development presets is rearranged in a total chaos order. I can not find any logic behind how it is organized. Is there a easy way to have it back in the order I hade it version 7.2. In the filesystem it looks ok but LR is doing something else.
I've been struggling with my entire computer freezing when Lightroom was left idle ever since the 7.2 update. After a lot of debugging including going to the extreme of replacing my video card I noticed when I tried an empty catalog I didn't have the issue.
So at least in my case I'm no longer seeing the issue in 8.1 after starting a new catalog and then doing File - Import From Another Catalog.
