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.

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?

I have 8 GB of VRAM.

Did you try with acceleration turned on?

First, I didn't realize that was off. So I turned it to Auto.
Second, I got almost the same crash. This time the progress bar got to about halfway, as usual, the fans kicked on to high speed, and the screen went black.
But one click on the power button got things back to running without a system reboot. And the operation did complete leaving the .dng file in my library.
Hmm. So something is still not right, but I suppose it is less wrong.

Fans going to high speed followed by system crash is a symptom that your CPU is overheating.

Or a symptom that there's been a severe enough crash that the system has lost control of the fan speed (on a Mac). This system has 8 CPUs.
It's hard to tell if the screen goes black before or after the fans go to full speed.
Regardless, Lightroom is doing something that ends in a system crash. Running a raw file through Photo AI or PureRAW does not do that.

It could do that, if enough heat is generated that the CPU (or GPU) overheats. The task of Denoise is more computationally intensive than any other task in Lightroom Classic by far, that generates heat, which must be dissipated. If there is any failure of the cooling system ... overheating and then computer shuts down. The fact that it doesn't happen in other software is irrelevant, their algorithms are different.

At this point, anything is possible.
What I typically see when the CPUs/GPU is being worked hard is the fans slowing ramping up as the heat load increases. In this case, all is quiet with the fans until the sudden crash.
If this system can't handle the work load, I'll be looking for more reports of this problem with iMac users.

You can quickly and definitively determine if the computer is overheating by downloading the free Intel Power Gadget:

Hello @BobRockefeller: AI-Denoise runs just fine on my Intel-based 2019 iMac with a Core i9 CPU and Radeon 580X / 8GB GPU. There is no overheating and I experience no crashes. You iMac Pro quite a bit more potent than my computer, so maybe there is indeed something wrong with the hardware? (fans clogged with dust? is that a thing? really just making guesses here.)

"fans clogged with dust? is that a thing?"
Very much a thing -- there are many posts here about LR overheating computers with improperly working cooling systems. My Macbook Pros (2016 and 2019) were very sensitive to that, and I had to take the 2016 to the Apple Store to get them to clean out the fan vents.

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.

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. 😉

Hi,
Thanks for the tip, but for me it didn't work. At first I thought great as I managed to process 2 single images, one at a time not as a batch of two. Tried for a third and almost finished and crash. As for fans cranking up, my case fans do a little and hold, temperature is maintained and does not increase. System and CPU is water cooled. (PC)
The more cleaning required, the harder the GPU is pushed. my AMD WX7100 8GB is pushed to 97 - 100% usage from the get-go and rarely drops below that depending on the image. Like your system my CPU usage is virtually zero and memory 3% of 64GB Corsair DDR5. Main system is AMD 9 7950x on an ASUS ROG Crosshair Extreme x670e and an RME HDPSe 32AES audio card.
I run other software apps that push my entire sytem and it remains solid. These are the first crashes that I have experienced since I had this system built six months ago. AI Denoise is definately doing something under the hood. I'm also running Photoshop and not Lightroom, but it is in Adobe Camara RAW that the sytem goes down when using AI Denoise. Have you checked your Lightroom Logs to see what they have to say, just a thought as I've just checked mine and there are a whole load of errors that have popped up and warnings and terminations at the end of the Logs over the past few days.

The original post has a "correct answer" and was affecting a Mac but it sounds like you're on Windows? So it's perhaps better to find a similar thread that is still open, or start a new discussion if you want to get eyes on your problem. 🙂
