We haven't changed the camera system, so I'm surprised it used to work and no longer does. Have you tried going back to a beta version to see if it still works?
I'm guessing the Intel HD Graphics 3000 is the problem. Can you force the machine to only use the NVIDIA GPU?
I have disabled Intel graphics processor and it wouldn't function at all again.
I also don't have the install or link to get the BETA version again as I got it through creative cloud in the first place.
You should still be able to see the beta version in the Creative Cloud app. Note that unlike other apps (which have a twirly arrow to show old versions), it's listed separately: current is "Character Animator CC" (1.1) and the previous is "Character Animator CC (Beta)" which will install Beta 6.
