I have just installed Unreal Engine 5.1 on my Macbook Pro M1 , macOS Monterey. I wanted to create a VR project, but it crashes at 10% of creating. I will put here the whole error, maybe someone has any idea, maybe it is a compatibility issue. AR, First person, etc, every other type works, except of VR. Thanks in advance

Hi,
I just had the same error message + crash (also macOS Monterey). After reading the log message, I changed
“vr.InstancedStereo=True” to “vr.InstancedStereo=False”
in the DefaultEngine.ini which is located in {Project Dir}/Config and now it’s working (I think, it’s still compiling shaders…)
Seems like it might be failing because GRHISupportsArrayIndexFromAnyShader is not set for Metal, and it’s required for instanced stereo. I have no idea if Metal is supposed to support it or not though.
What is the use case for running VR on a Mac? I don’t think any current headsets or runtimes support it.
I’m hoping to (eventually) be able to use my M2 Mac do develop for Quest 2 and Quest Pro. So I just need to be able to run the editor without to many flaws, and be able to compile for the Quest.
Seems the regular OpenXR plugin works, but not the MetaXR plugin, and thereby not the Quest Hand tracking and face- and eye-tracking on the Pro.
It’s very unlikely that the MetaXR plugin will get support for MacOS. If you intend to use any of Meta’s device specific features, you have to develop on Windows, as most of them are only supported through their plugin.
