I used to have similar problems, eventually I got it working. One of the videos (I think) helped was this one: Best setting for Oculus Quest Unreal Engine (youtube.com) . Try that guys settings tick box by tick box. Unreal 5 is INSANELY particular about android settings and render settings for it to work properly.
Also, quick launch from the editor usually doesn’t work for me (I get black screen without launch) but packaging out shipping builds, uploading to a release channel and installing from meta quest account does work. That is only possible if your game is already accepted on meta app store/app lab though.
Quick Launch always worked in UE 4.27. It’s hit and miss in UE5. Since shipping builds work I just do that now all the time.
