Major hardware crash attempting to use Lightroom Classic 12.3 Denoise

Invoking Denoise on an unmodified Fujifilm X-T4 RAW file (.RAF) results in a hardware crash. The scene goes black and the system must be restarted with a hardware reset.

 

I'm running a 2017 iMac Pro with macOS 13.3.1 (Ventura).

 

Has anyone else seen this? Or can suggest what I need to be looking for?

OK, I fixed it. But I did two things at the same time, so I don't know which one did it. I deleted Lightroom's preferences. And I vacuumed out the cooling slots on the back of my iMac Pro.

 

When Denoise cranks up, I see very little CPU use (it's using the GPU for the most part) and the fans stay pretty quiet although they do increase in speed some.

By @Erich32593464bdtl

Presets? or Preference file?

If Presets, why? And how does that relate to this post?

    If you want to get to the bottom of it, you could try and retrieve the old preferences from a backup and put it back. 😉

    You might want to make sure you have installed the latest version of the driver for your video card.

    It's a Mac. So all that happens with System updates.

    Please post your System Information as Lightroom Classic (LrC) reports it. In LrC click on Help, then System Info, then Copy. Paste that information into a reply. Please present all information from first line down to and including Plug-in Info. Info after Plug-in info can be cut as that is just so much dead space to us non-Techs.

     

    Mostly interested in the GPU info.

     

    Also, how much VRAM?
