Super Resolution causing odd texture over image.

Issue: Super Resolution causing odd texture and artifacting to appear over the entire image, when previously it did not.

• Lightroom Classic Version Number: 12.0.1
• OS Version Number: Windows 11 Home 21H2 22000.1219

Steps to reproduce:

1. right click on image in library and click enhance
2. With Super Resolution checked, the image preview shows the horrible texture/pattern
3. Final result shows the pattern as well.

Expected result: An image with great detail and minimal if any artifacting at double the original file's resolution.
Actual result: Horrible artifacting and incorrect color as though looking at the image on an old CRT screen that makes the image completely unusable, even when viewed at the original image's size on the screen.  

I tested this with an image that had already had successful results using Super Resolution previously. I am uncertain which version I had been using when the Super Resolution result was successful.
