Bug / Crash Actors do not render when manually rendering camera

[nickhudson4]

Actors do not render when manually using Camera.Render() and rendering to a texture. Steps to reproduce: 

1. Create actor in scene and place camera.
2. Add RawImage to scene to show camera output
3. Disable camera component.
4. Create script

Code:

public class ObiTester : MonoBehaviour
{
    public Camera Camera;
    public RawImage Screen;
    public RenderTexture SourceTexture;

    private void Awake()
    {
        SourceTexture = new RenderTexture(1920, 1080, 1);
        Camera.targetTexture = SourceTexture;
        Screen.texture = SourceTexture;
    }
    private void Update()
    {
        Camera.Render();
    }
}
