Blender3.0 ShadowCatcher problem

Hi, I recently noticed a bug in shadow capture in Blender3.0
After using optix noise reduction, there will be black spots in invisible places,Blender2.93 does not have this situation,This kind of black spot needs to be copied about 30 layers in the graphics processing software to see it。With open Image denoise, there is no such wide range of black spots
I don’t know English, the above is the result after translation
