Quest 3 App Crashes After First Launch and Runs Only in 2D View (UE 5.2.1 with OpenXR Plugin)

[shravanum01]

Hi everyone,

I’m working on a VR project for Meta Quest 3 using Unreal Engine 5.2.1 and targeting Quest software version 78.102.

Initially, I was using only the OpenXR plugin, but the build was launching in a 2D windowed view inside the headset instead of full VR. I later found a temporary workaround by enabling the deprecated Oculus VR plugin alongside OpenXR — with both plugins enabled, the app started running properly in VR.

After the automatic update to version 74, my game no longer launches in VR mode as expected. Instead, it runs in windowed mode and closes after a few seconds, despite all configurations being set up correctly. Everything was working perfectly before the update. I am using Unreal Engine 5.2 on macOS Sonoma, with Developer Hub updated. Has anyone found a solution to this issue? Please advise. The biggest issue is that Meta does not support the MetaXR plugin for macOS, so I can’t simply downloa…

However, I’ve now run into a new issue:

• After sideloading the APK, the app runs correctly the first time.
• But during the first session, it crashes mid-runtime.
• After the crash, the app disappears from the Unknown Sources tab.
• It still shows up in the menu bar at the bottom of the Quest UI, but when I click it:
  • The app either does not launch at all, or
  • It launches in a 2D black UI with passthrough-related options like:
    • “Exit Passthrough”
    • “Minimize”
    • “Enlarge Screen”
    • “Exit”

I’ve tried rebooting the device, uninstalling/reinstalling the app, and clearing app data, but nothing brings it back to normal VR mode.

Has anyone else faced this issue?
Could this be caused by recent Meta updates, plugin compatibility, or something specific to OpenXR behavior in 5.2.1?

Any guidance or solution would be greatly appreciated.

Thanks in advance!
