VR Mode & VR Preview issues

I have a quest 2 linked with a cable and it is shown in ADB devices.

I did all the necessary initial setup steps provided by Oculus and Unreal.

I installed Android Studio, Java se8, Visual Studio Community 2019…

I did everything by the book… I even re-installed everything once.

VR preview is always grayed out and VR mode is simply missing… no button at all…

What can I do to solve this problem?
