Did you add the camera new from scratch to CamUniversal?
Please try this. Perhaps the camera source filter or an interim filter has renamed.
Please, try first always without video/audio codecs.
Thanks for the suggestions. Its up and running again.
FYI: Removing and adding the cameras back got one working with the second having a black screen with a rectangle of green fuzzy pixels on the bottom.
After I stopped and restarted camera preview both it all came good and was operating the same after reboot tests.
