Lightroom Classic Denoise Spins but never Completes (worked earlier)

[lbeefus]

The new denoise feature worked for a while today, but now it spins and never completes. It seems specific to images with AI-based masks. I let it run for half an hour and never saw an error. Is there a log anywhere that can help diagnose the issue? I'm have a 24gb VRAM NVidia 3090 ti, so I doubt the GPU is an issue.

Can you advise what edit features you are applying in LrC to the raw image prior to invoking the Enhance DeNoise feature?

You could check first if your GPU drivers are up to date.

Adobe advises to use AI-Denoise early on in the process, but I've run it on older photos with AI-based masks and it worked, but does take longer. (I'm on a Mac and it sounds like your on Windows, so our experiences probably won't match.)

Just tried it on an image with AI masks and it worked fine. Maybe somebody with a similar machine needs to test. Alex's advice of making sure the GPU drivers are up to date is definitely a good thing to check.

To build on @alexskunz's reply, most problems with AI masking are caused by older, buggy graphics drivers. Try updating your graphics driver by going directly to the manufacturer's web site:
