No active UnityEngine.XR.XRInputSubsystem is available. No active UnityEngine.XR.ARSubsystems.XRSessionSubsystem is available

I remember encountering a similar problem if not the same one using Unity6 (6000.0.33f1). Uninstalling Unity Remote was what has solved the problem.

I created a new project on Unity6 (6000.0.36f1) and followed the given configuration settings. I don’t know what else I’m missing. It’s been building just fine and I’m no longer getting a black screen on my phone but these errors still keep showing up after playing:

someone might be having a similar problem to mine. please note that i’m working on an AR project using Unity6 (6000.0.36f1).

I don’t know which one helped it but I installed both ARKit (although i don’t plan on working on ios… i’m building on android) and XR Interaction Toolkit. Both you will find from Window → Package Manager (Unity Registry).

Also ticked the box for XR Simulation under the Windows, Mac, Linux Settings. You will find it from Edit → Project Settings → XR Plug-in Management → (click the one with a monitor icon).

hope this helps! :smiley:
