Lightroon Classic Denoise issue

Running Lightroom Classic Ver. 14.4.

Nikon D7500

Windows 11 Home Ver. 24H2

Windows, Lightroom, and the Display Drivers are all the latest versions.

When I use the Denoise feature, the image comes out completely messed up. Editing this photo in raw:

Denoise feature gave this result:

I tried a number of photos, and also got the same result on an old photo that successfully denoised with a older version of LrC.

My workflow is Import>Develop>Denoise. I get no error messages. The denoise result looks the same in LrC as it does after I export the image as well.

I saw some previous posts that said lightroom didn't like dual GPUs, so I also tried disabling UHD Graphics 630. that did not help. And I reset my preferences. That did not help.

Any thoughts on a fix?

Thank you in advance.

Graham.
