I have currently found a work around for this issue.
In the link below there is the code what have worked for me.
What I do is just reseting the old value of the touch state. Remember it is important with IEnumerator else the code won't work.
I hope this helps.
Code Work Around:
public void Start()
{
StartCoroutine(ResetValueOfTouch());
}
IEnumerator ResetValueOfTouch()
{
TouchState newTouchState = new TouchState();
newTouchState.isPrimaryTouch = false;
newTouchState.pressure = 1;
newTouchState.touchId = 1;
InputSystem.DisableDevice(Touchscreen.current);
InputState.Change(Touchscreen.current.primaryTouch.phase, (byte)UnityEngine.InputSystem.TouchPhase.None);
InputState.Change(Touchscreen.current.primaryTouch, newTouchState);
yield return new WaitForSeconds(0.1f);
InputSystem.EnableDevice(Touchscreen.current);
}
