Question

AI denoise has a severe memory leak

Lightroom Classic's AI denoise has a severe memory leak, causing crashes and extreme slow execution / unresponsiveness. The only way to get the memory usage down is to either wait until LRC crashes or try to close the application.

How to reproduce:
Open the task manager and note the current memory usage.
Use AI denoise on a couple of images

Expected result:
The memory usage should go back to about the original usage after the AI denoise is done

Actual result:
The memory stays at a unhelthy level. The more images that are denoised, the higher the memory usage.

Please do the LR menu command Help > System Info and copy/paste 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.
