    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);
    }
