Resolution Note:
Some phones like Google Pixel 7, when touching screen produces an event which is both touch and pen.
In your project you have TouchSimulation script assigned to Box game object, as stated in https://docs.unity3d.com/Packages/com.unity.inputsystem@1.0/api/UnityEngine.InputSystem.EnhancedTouch.TouchSimulation.html, it produces events from Pointer types, so in this case since Input System receives both touch & pen event from backend, TouchSimulation treats it as two fingers.
Not sure why you're using this script, because EnhancedTouchSupport works without the need of TouchSimulation.
In other words remove TouchSimulation script
