  1. Resolution Note:

    User error.
    See documentation for Finger.currentTouch:
    https://docs.unity3d.com/Packages/com.unity.inputsystem@1.1/api/UnityEngine.InputSystem.EnhancedTouch.Finger.html

    Users code doesn't check the "valid" property for the touch and the exception is thrown in cases when the current touch is invalid.
    The issue only happens on Android, because the code in question is Android-only (is behind UNITY_ANDROID define).
