Crash when using level streaming

[Anonymous]

Using Oculus UE4 version 4.25.4.

If I add a sub-level set to initially loaded and initially visible I get a crash in:

Thanks for any help/advice

Did you find a solution?

I am using Quest 1, and One of my project crashes with the error "Ensure condition failed: Scene->GetShadingPath() != EShadingPath::Mobile" when OpenLevel is used, and another project crashes with LoadStreamLevel after OpenLevel.

Some people say they got their app crashed on level transition with Quest 2, and they fixed it by enabling Support arm64 option instead of Support armv7. I tried both but it didn't work for me.

You can comment out the codepath in 

if (PrimitiveSceneInfo->NeedsReflectionCaptureUpdate())

 with the ensure that fails, or simply #ifndef PLATFORM_ANDROID it.
