Escape key not working

Hello. I hava a problem with my pause menu. I want to open it when escape key is pressed but it does nothing. I tried another keys and it worked so i don't know where the problem is.

 using System.Collections;
 using System.Collections.Generic;
 using UnityEngine;
 
 public class myPause : MonoBehaviour
 {
     bool isPaused;
     public GameObject Pause;
 
     void Start()
     {
         isPaused = false;
         Pause.SetActive(false);
     }
 
     void Update()
     {
         if (Input.GetKeyDown(KeyCode.Escape) && isPaused == false)
         {
             Pause.SetActive(true);
             isPaused = true;
         }
         if (Input.GetKeyDown(KeyCode.Escape) && isPaused == true)
         {
             Pause.SetActive(false);
             isPaused = false;
         }
     }
 }
