I need to click after unpausing game to hide the cursor

Hello I got problem with my pause game menu, my mouse keeps visible even when i press ESC again (it disappear for a half of a second than it again gets visible) but my mouse won't dissappear even when i build the game... :D (so its not in the editor...) it only goes invisible after clicking with left click (in built game) anybody got any ideas? Thanks for any help! Here's my code:

 using System.Collections;
 using System.Collections.Generic;
 using UnityEngine;
 using UnityStandardAssets.Characters.FirstPerson;
 
 public class PlayerController : MonoBehaviour
 {
 
     public GameObject ESCMenu;
     public bool ESCMenuVis;
     FirstPersonController firstPersonController;
     [SerializeField] GameObject player;
 
     void Start()
     {
         ESCMenu.SetActive(false);
         ESCMenuVis = false;
         firstPersonController = player.GetComponent<FirstPersonController>();
     }
 
     // Update is called once per frame
     void Update()
     {
         
         if(Input.GetKeyDown(KeyCode.Escape)) 
         {
 
 
             if(ESCMenuVis == false) 
             {
                 ESCMenu.SetActive(true);
                 ESCMenuVis = true;
                 Cursor.lockState = CursorLockMode.None;
                 Cursor.visible = true;
                 Time.timeScale = 0f;
                 firstPersonController.ESCMenuOpened = true;
 
             }
             else
             {
                 ESCMenu.SetActive(false);
                 Cursor.lockState = CursorLockMode.Locked;
                 Time.timeScale = 1f;
                 firstPersonController.ESCMenuOpened = false;
                 ESCMenuVis = false;
                 
             }
         }
 
 
         if (Input.GetKeyDown(KeyCode.R))
         {
             Debug.Log(Cursor.visible);
         }
     }
 
     public void SetInActiveMenu()
     {
        ESCMenuVis = false;        
     }
 
     public void SetCursorActive()
     {
         Cursor.lockState = CursorLockMode.None;
     }
 
     public void SetTimeNormal()
     {
         Time.timeScale = 1f;
     }
 
     public void EnableRotation()
     {
         firstPersonController.ESCMenuOpened = false;
     }
 
 
 }
