Can not deploy game to my Oculus Quest

Hi there, 

I am new in the community forums and hope some of you can help me out. 

I am currently working one a 3D game with Unity. I want to deploy my game to my Oculus Quest 1. 

I do have all the necessary assets and settings. I know about them, because a couple of weeks ago it worked quite well. In the meantime I do not have done any update on the Quest, Unity or the Hub. 

When I click Build and Run in Unity, it try to open my game on the Quest, but nothing happens. In Unity says "Build successful" so no error message there. On the Quest it says "game exits repeatedly". 

Any idea what to do?
