VR doesn't work if there are multiple scenes

Target Platforms XR

First I`ve only had 1 basic scene and everything worked fine (still does).

Now Ive have a menue in where you can input streaming data and stuff (VR support turned off). When I hit the start button, the "basic scene" is loaded and I turn the VR support back on. While VR is indeed activated, nothing seems to work. The HMD's position is neither tracked, nor do I receive any kind of picture. Also there arent any errors.

Ive tried turning the VR on in an Awake() method and also right before loading the scene, in case the VR support wasnt enabled fast enough. But that didn`t change a thing.

Worth mentioning:
Im using the OptiTrack Motive Plugin to stream my HMDs position and a couple of objects to Unity. Also I`m using Leap Motion(turned off right now, cause no 5.6 support yet). Im using Oculus CV1.
Again, if I start the scene WITHOUT the menue beforehand it works like a charm.

Any suggestions?

Edit: Seems like it can`t find the HMD. Still, no idea how to solve this.

Solved: You can`t use VRSettings.enabled in Awake(). Use it in Start()
