Issue with Meta Interaction SDK v74 on Oculus-5.5-v74 Unreal Engine Fork

Issue Description

 

I downloaded the Meta Interaction SDK (version 74) and integrated it into the Unreal Engine fork oculus-5.5-v74 from GitHub.

The integration works correctly inside the Editor, and VR Preview runs without any issues.

However, when I package the project for Quest and install the APK on the headset, the application:

launches,

shows a black screen for less than a second,

 

then immediately crashes/auto-closes.

When I disable the Meta Interaction SDK plugin and rebuild the project, the packaged application works normally on the device.

This confirms that the crash is directly caused by the Interaction SDK during runtime on the Quest.

What I Have Already Verified

The plugin is properly added under /Plugins/runtime/OculusInteraction.

Engine fork version matches the Meta SDK version (both v74).

No conflicts in Editor logs.

No errors during packaging.

The crash happens only on device startup, not in VR Preview.

Expected Behavior

The packaged app should run the same way it does inside VR Preview.

The Interaction SDK should not crash the application on Quest when the correct version is used.

Request

Could you please advise on:

  1. Whether Meta Interaction SDK v74 is fully compatible with the fork oculus-5.5-v74-openxr-asw-ffr.
  2. Any additional setup required to ensure correct initialization on Quest (permissions, XR loader, manifest changes, MetaXR modules, etc.).
  3. Whether this is a known issue for v74 of the SDK.
  4. If this fork requires a specific Interaction SDK variant different from the public one.
