I had the same problem and I posted it but don’t remember the title now. I think that moving the enhance sharpness slider to max removed it. I’ve only had it on one picture.
The “Enhance Sharpness” slider affects the number of the red hot spots with 0 sharpness the largest number and size of red spots whereas maximum 1.0 leaves only the most picture central clump of red hot spots but doesn’t totally eliminate them.
This is an issue that we are aware of and are working to resolve this issue in the update to DeNoise AI. That release should come out in the next few weeks, though we do not have a set timeline at this point.
