RayCastHit.textureCoord not working on builded game

I’m making a FNAF like game where you can click on the screen of a computer to make the actions. The screen have it’s own UI. When I’m in unity everything works properly, but when I build the game it doesn’t work.

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.UI;
using UnityEngine.EventSystems;

public class RenderTextureRaycast : MonoBehaviour
    public RectTransform UICanvas;
    public GraphicRaycaster screenCaster;
    public LayerMask screenMask;
    GameObject mainCamera;
    PointerEventData pointerEventData;

    public Text debugText;

    private void Start()
        mainCamera = Camera.main.gameObject;
        pointerEventData = new PointerEventData(EventSystem.current);

    private void Update()
        Ray ray = new Ray(mainCamera.transform.position, mainCamera.transform.forward);
        RaycastHit hit;
        if (Physics.Raycast(ray, out hit, 3, screenMask))
            List<RaycastResult> results = new List<RaycastResult>();
            Vector2 virtualPosition = new Vector3(hit.textureCoord.x, hit.textureCoord.y);
            virtualPosition.x *= UICanvas.sizeDelta.x;
            virtualPosition.y *= UICanvas.sizeDelta.y;

            pointerEventData.position = virtualPosition;
            screenCaster.Raycast(pointerEventData, results);

            debugText.text = "Texture coordinate: " + hit.textureCoord + "

Screen position: " + virtualPosition + "
Event system: " + pointerEventData;

            foreach (RaycastResult result in results)
                if (Input.GetMouseButtonDown(0))
                    ExecuteEvents.Execute(result.gameObject, pointerEventData, ExecuteEvents.pointerDownHandler);
                    ExecuteEvents.Execute(result.gameObject, pointerEventData, ExecuteEvents.pointerClickHandler);

                if (Input.GetMouseButtonUp(0))
                    ExecuteEvents.Execute(result.gameObject, pointerEventData, ExecuteEvents.pointerUpHandler);

Does anyone knows how can I solve this problem? Thanks!

I know this is very late but I found your problem! The issue has nothing to do with your code, it’s actually a Mesh issue. Go to the raw Mesh in your asset viewer and check (Read/Write) in the import settings! This was driving me crazy for days so even I hope this can help anybody out there.
