'MRTK hand tracking does not work properly with Oculus Link

I am creating a VR game in Unity. I am having a problem with hand tracking not working properly with PCVR (.exe build) only.

The detailed situation is as follows

  • I have developed a game using Unity, MRTK, and Oculus Integration, running on Oculus Quest2.
  • When playing the game via Oculus Link with a PCVR(.exe) build, the following situation occurs.
    • Hand tracking works correctly in the scene immediately after startup.
    • When hand tracking is performed after the scene transition, the hand mesh probably appears at (0, 0, 0) and does not move.
    • The Dynamic Bone Collider attached to the hand is working, so it does not seem that the hand coordinates are not tracked completely.
    • The controller works fine both after startup and after transition.
  • Hand tracking works fine in the APK build and in the mode where I press the Play button in Unity.

The version is as follows

  • Oculus Desktop App: 38.0
  • Oculus Quest2: 38.0
  • Unity: 2021.2.7f1
  • Oculus Integration: 38.0
  • MRTK: 2.7.3

I don't know if this is the right way to do it, but hand tracking now works.

Removed the following #if UNITY_EDITOR and #endif in OVRSkeleton.cs > Update.

#if UNITY_EDITOR
        if (ShouldInitialize())
        {
            Initialize();
        }
#endif

Do you mean by commenting out that code snippet it is possible to use hand tracking on a PC build using OVRCameraRig and Oculus Integration?
