VR Preview broken on big UE5 Projects (Oculus Quest 2)

Hello so I do not know if Im setting up something wrong or what but I do only get VR Preview on simple projects for example a random 3D model or the VR basic Template.

when I try to open for example something bigger such as Electric Dreams Env OR Valley Of the Ancient it doesn’t show up any help for this ? or is it because the Oculus quest 2 will not handle it ?
