Kernel Panic & Lightroom Crash

[Tommyjuddyphoto]

Using Adobe LR Classic and Mojave 10.14.4. I am having repeated instances of Lightroom crashing and/or Kernel Panic (when using the develop module).

Here is the crash report from the most recent crash.

Not only this, but I can no longer update LR through CC as CC has crashed and won't reopen. 

I have tried steps from so many other posts/suggestions already and nothing fixes this. I don't have any anti-virus software on this mac. PLEASE HELP. This is very frustrating and I can't get any work done!

Have a look at this Adobe help article.

Same problem here. The issue appears to be related to the GPU acceleration - if I disable this I can use the Develop module - if I do not disable it the fans spin up, full CPU usage and a total freeze and restart of the Mac. Same kernel panic crashes happen in Adobe Camera Raw. As a photographer who has nearly half a million images in a Lightroom catalog this is problematic.

If turning OFF GPU works, it's a GPU bug and you need to contact the manufacturer or find out if there's an updated driver for it.
