    Hello,

    I am using Unity 2019.3b7, ARFoundation, ARKit. The produced build of the iOS is built as library which is still in beta. I am on Catalina, Xcode 11, iOS 13.1. My project is AR project on unity side.

    When I try to shutdown the AR experience, I basically make a call to the Unityframework to unloadapplication and I get following crash.

    ArgumentNullException: Value cannot be null.
    Parameter name: _unity_self
    at UnityEngine.IntegratedSubsystem.Stop () [0x00000] in <00000000000000000000000000000000>:0
    at UnityEngine.XR.ARFoundation.ARInputManager.OnDisable () [0x00000] in <00000000000000000000000000000000>:0

    Anyone have any idea what is causing this? Thank you in advance!

    Hi @bambamyi,
    I am facing a similar issue while closing our AR app for Android made with Unity 2019.2.0 and AR Foundation 2.1.4. I see these exact logs in the console. Also, when I quit the app and see this error in the logs, and when I open the app again, it crashes at the start. If I start the app after the crash, it starts normally.

    It seems like a bug with AR Foundation 2.1.4. Did you manage to solve your issue?

    I have the same issue when using the quitApplication method on iOS with the code 0.
    For information I'm using AR Foundation 2.2.0 Preview 6.
