Hello, I'm developing an app that starts in desktop mode and allows you to view 3D models of your choice in VR at a later time. It works perfectly in the editor and standalone builds, but in UWP (the one I need), I encounter either a white screen when no headset is connected or the mixed reality portal opens with a black screen. Have I missed a step? I just unchecked the "Initialize XR on Startup" option. I'm using Unity 2022.3.0.
