Hello Everyone:
I also have the same issue. So, I created a workaround for me and those that need to use the camera in the HoloLens by using MediaCapture. The workaround allows to take, save, and display photons in the HoloLens and it satisfies my needs. So, I am sharing this here to maybe help someone else that can't wait like me (I discovered this issue last Friday and it seems that it is going on for a long time):
