When I first launch my game, a pop-up window appears with Camera Permission, and when I confirm, an exception is thrown:
AndroidPlayer(ADB@127.0.0.1:34999) Exception: No such proxy method: UnityEngine.XR.ARCore.ARCorePermissionManager.OnPermissionGranted(System.String)

However, the second launch is normal.
