Vray 6 Shadow Catcher Problems / Trash Pixels

All of a sudden I’m getting trash pixels in my renders. Not in the VFB, in the saved image from the VFB. Using Shadow Catcher object. See image. VFB raw render on the right, saved image loaded into Photoshop on the left. And I can see the Vray Light shape even though its set to invisible. These trash pixels are “not” in the alpha channel thankfully.

Max 2022 (latest updates)
Vray 6.00.06

Would it be possible to attach the scene?
