Meta Quest 2 - 3 seconds of Sound but only Black Screen

I wanna try Squadrons on VR (Meta Quest 2) but it's not working at all. I have the game on Origin and followed all the steps like open Steam VR, connect with a cable etc. So I hear the game sound for like 3 seconds, I don't see anything, just a black screen and then the music stops and that's it. I clicked like a million times in the game on "Use VR" then it says I should press ß to calibrate, then I hear 3 seconds of sound and bang.

It's so frustrating cause I try it now the 2nd weekend in a row and just wanna play.

Any idea that REALLY helps?
