Run Tilt Brush Open Source code on Oculus Rift S

I tried to download open source tilt brush project from github and run it in Oculus Rift S. But It shows "Tiltasaurus says Failed to detect VR as following picture and It does not show any error in the console. And the other thing is I still can run other apps build by me with the same Oculus Rift Headset. Any solutions?

Have you found any solution to this?
I am currently having the same problem to run TiltBrush OpenSource on Oculus Rift S. Other Apps runs okay.
