builting to 64 bit android

Hi, I created an Android app. When I build it to 32 bit it works fine but when I build it to 64 bit the touch does not work. I tried to change all kinds of functions but once I install the app on my phone the touch does not work.
(UI button working properly)
Please help me, I've built a lot of apps and it never happened to me

 

sure, i have to say that I tried all the possible functions...
What is particularly strange is when i try it on unity remote- it works, but when i install the APK the touch not working (i have ui buttons and they work) and as i said when i built it as 32 bit everything works great but when i built it as 64 bit the problem start...
i created many games app and it never happend to me...

anyway' here is part of the code


void Update()
{

Ray ray = Camera.main.ScreenPointToRay(Input.mousePosition);
RaycastHit hit;

if (Input.touchCount > 0)
{
Touch touch = Input.GetTouch(0);
if (touch.phase == TouchPhase.Began)
if (Physics.Raycast(ray, out hit, Mathf.Infinity))
{
Debug.Log(hit.transform.gameObject.name);

if (hit.transform.gameObject.name == this.name)
{


if (OnBlockPressed != null)
{

OnBlockPressed(this);

}


}

}
}
}
