LR Classic 13.4 crashes Mac Pro using Denoise AI

Vacuumed all air intakes, running Sonoma 14.6 on 2019 Mac Pro, LR Classic 13.4. 

Running Denoise AI has crashed Mac from the start, but crashing (hardware shut down) has become 50% to 100% in the past couple of weeks. 

Apple Support asked me to open Activity Monitor and we watched LR use 2% to over 215% of % CPU while running Denoise (it crashed again). He surmised that I need to Unistall and Reinstall Lightroom, theorizing a fresh install would remove any possible corruption. He wanted to rule out software corruption before assuming it was a hardware issue (I.e. Intel vs  M2 chip.

The question is: can I SAFELY uninstall and reinstall Lightroom Classic without jepordizing my 200,00 plus catalog of processed photos, and my entire catalog?

In other words, if I uninstall Lightroom and then reinstall, will it find all of my correctly processed photos, data, etc. When I reopen Lightroom, will everything look they way it is supposed to?

I do not want surprises. All of my data is backed up to 3 hardrives using CCC.

@jonholcombe: "Sonoma 14.6 on 2019 Mac Pro, LR Classic 13.4."

 

Your Mac likely has an AMD Radeon 5000-series GPU. Please confirm by doing the LR menu command Help > System Info and copy/pasting the entire contents here so we can see exactly which versions of hardware and software LR thinks you're running and important LR options that are set.

 

If you do have one of those GPUs, you're out of luck: Apple released a buggy graphics driver in LR 14.4.1 and AMD and Apple haven't released a fixed driver yet.

    You are correct, my MAC has two AMD Radeon Pro 580X 8 GB PCI cards. Can you recommend a better, more current, upgraded, PCI card(s)? I appreciate the help.

    You probably need to disable one of the Radeon cards. Having two active is a recipe for disaster.

      An Apple tech suggested I try this since I am unable to use Denoise without crashing my 2019 Mac Pro/

      Will I lose my catalog of 200,000 photos or lose my processing data to my RAW files?

      Using LR Classic 13.4.

      You can uninstall and reinstall LR Classic without losing the catalog.  The catalog file is a separate data file.  LR Classic is a program file.   That said, please have a backup system in place.  You should be creating catalog backup files from Lightroom Classic and then copies of those catalog files should be backed up along with all of your other important files.   With backups in place, the worst that can happen is that you will have to retrieve a recent one one and open it.  All your image files are kepts separately and should also be backed up.
