Green/yellow noise shows up when I run denoise - except on a few small square areas of the photos.

I'm not sure what is happening. I've tried to run denoise on a few photos, they all turn out like this. That one little square that isn't green still changes if I use other editing sliders. It's like the denoise worked on a couple areas and turned everything else into green disco snow.

I'm on windows, using Lightroom 9.2, x64

Things I have tried:

Windows is up to date

GPU Drivers are up to date

Have restarted Lightroom

Exporting the photo retains the green, so it's not just a visual glitch

Happens with multiple photos
