UE 5.1 VR Template crash (RT Shadows ON + Instanced Stereo ON)

General Feedback & Requests

I have a really weird crash that is I can reproduce on a fresh new project using the VR template:

The editor crashes immediately after I touch my right VR controller to teleport if I have RayTraced Shadows + VR/Instanced Stereo enabled.
The left stick works fine to turn, just crashes when I use the right stick.
If I disable either RayTraced Shadows or Instanced Stereo, it works fine.

Is this a known issue/limitation? Is there a workaround? Thanks!

Repro steps:

  1. Open a new VR template
  2. Disable Forward Shader
  3. Enable: Support Hardware Ray Tracing, Raytraced Shadows
  4. Launch VR Preview.
  5. Move the Right Joystick forward (to teleport) and the editor will crash.

I also have same problem on my VR project, and thanksfully I was using lightmass so I turned off Hardware Raytracing then I solved my problem. For now, I coud not found any solution to this problem without turning off the raytracing.

Same proble here. if you just disable ray tracing shadows it works.
the problem is the mesh renderer on the cylinder in NS_TeleportRing.
iā€™m using only the ring at the moment, looking for a stable solution.
hope it helps
