Unhandled exception. System.NullReferenceException

[devang-ajnalens]

Hello,

I added below code :

` DesktopMaterial desktop = new DesktopMaterial();
desktop.Start();

SK.Run(() => {
desktop.Step();
Mesh.Cube.Draw(desktop.Material, Matrix.TS(0, 0, -0.5f, 0.2f));
});`

and getting exception as below :

Unhandled exception. System.NullReferenceException: Object reference not set to an instance of an object. at StereoKit.DesktopMirror.DesktopMaterial.Start()

Please let me know anything I'm missing?

Thanks,
