I cant launch the level as "vr preview"


why

May I suggest you give a little more information, to help people help you.

E.g. What VR plugins do you have enabled?
What VR system do you have connected?
Have you modified any project settings to enable Start in VR for example?
Have you started steamvr or your headset’s client (in my case I start the Oculus client BEFORE starting up my unreal engine VR project?

So, what have you done, so people can work out what you haven’t done.

Also, make sure your GPU and VR headset drivers are up to date.

What VR plugins do you have enabled? no vr plugins whatsoever
What VR system do you have connected? oculus quest 2
Have you modified any project settings to enable Start in VR for example? i did, but i’ve returned the setting back since it didn’t help
Have you started steamvr or your headset’s client (in my case I start the Oculus client BEFORE starting up my unreal engine VR project? yes i did, steamvr is running in the windows along with it’s opened on the headset’s monitor

I have steamvr, openxr and oculus vr all enabled in my project plugins settings.
Try enable those, and probably need a restart and see how that goes.
Also enable start in VR again maybe.
Is the project a VR project (some sort of VR pawn in it)?

ah yes i see it is some sort of vr template map so that should be ok.
