Could not connect pins - RenderStream()

UnityEngine.WebCamTexture:Play()

This error keep showing up on my editor but when I build it on android and run on my android emularor. It works fine. I try to search for answers yet it didnt get me to the point. I also did try to contact unity yet the engrs. talk to me like a computer. YET, I LOVE UNITY. I am really frustrated to make this thing work asap as I am making a POS and login system.

I have one diagnoses for this because it work like a charm when I was in Unity 5 not 5.6. I think something in the Device PID, I need to force any connection to the camera device which is not unity to terminate and connect unity to that camera device. I forgot to shutdown something that is using that PID or hardware device.

Could somebody once told me and to those who is also stuck in the same problem yet manage to make it work. Thank you in advance and hope I will get an answers.
