Could not connect pins - RenderStream() to Intel Realsense D435

I am trying to play around with this camera in unity, but when I try to use it’s RGB features, I get the following error:

Could not connect pins - RenderStream()
UnityEngine.WebCamTexture:Play()
RenderCamera:Start() (at Assets/Scripts/Camera/RenderCamera.cs:75)

where the script is as follows:

72    webcamTexture.deviceName = devices[RealsenseD435].name;
73    Renderer renderer = GetComponent<Renderer>();
74    renderer.material.mainTexture = webcamTexture;
75    webcamTexture.Play();

So far I know that the Intel Realsense D415 works with this exact same project.

any help or experiences with the D435 would be greatly appreciated!

I have same error with Unity 2018.4.11f1 and Intel RealSense D435i and WrnchAI. The Intel SDK for Unity works inside Unity, but not the WrnchAI desktop demo scene. Any idea?
