Bug [HTC Vive Pro] Build not receiving Mouse + Keyboard Input

Hello,
My project is on Unity 3d, but this specific scene is a 2d configuration menu.
I have a Menu displayed on the computer Screen through a Canvas.
The Menu elements are clickable in the Editor but not on the Build/Desktop App.
Clicks and Keyboard are not interacting with anything on screen as soon as I open the App.
How do I fix this?

Things I've done:
- Reset the Event System
- Set the Controllers System Key to None
- Add and Delete the [CameraRig] and [SteamVR] Components



The Headset is HTC Vive Pro Eye
SteamVR 1.23.7
Unity 2021.2.5f1
