Problems with EpocCam and Camo

I am trying to use a USB connected iPhone 8 Plus with XSplit Broadcaster as a 4th video source.
I have tried using Elgato’s EpocCam or Reincubate’s Camo. Both seem to install it’s drivers fine, and Broadcaster recognizes each as a video source. But after a few minutes, the image freezes.
Is there a setting that I am not getting correct?
Any help would be appreciated.
