Game stops for a few seconds after interacting with an object

Hi there, im trying to establish a system for object interaction, but every time player goes inside the trigger and i press "E" the game stops for a few seconds and then the UI dialog appears, this only appens the first time i try to do this. I would really appreciate any coments on this. I place this script into the object: using UnityEngine; using System.Collections; using UnityEngine.UI;

 public class Object_Interaction_Dialog : MonoBehaviour
 {
     public string[] _Dialog_Database;
     public int _Speech_Number = 0;
    
     public Text _Dialog;
     public GameObject _Dialog_Box;
     public ThirdPersonMovement _ThirdPersonMovement_Script;
    
     public void Dialog_With_Gate()
     {
 
         if (_Speech_Number < _Dialog_Database.Length)
         {
             _Dialog.text = _Dialog_Database[_Speech_Number];
         }
         else
         {
             _Dialog.text = "";
             _Speech_Number = 0;
             _Dialog_Box.SetActive(false);
             _ThirdPersonMovement_Script.enabled = true;
         }
 
         _Speech_Number++;
 
     }
     public bool inTrigger;
 
     void OnTriggerEnter(Collider other)
     {
         inTrigger = true;
     }
 
     void OnTriggerExit(Collider other)
     {
         inTrigger = false;
     }
 
     void Update()
     {
         if (inTrigger)
         {
             if (Input.GetKeyDown(KeyCode.E))
             {
                 _ThirdPersonMovement_Script._Horizontal = 0;
                 _ThirdPersonMovement_Script._Vertical = 0;
                 _ThirdPersonMovement_Script.enabled = false;
                 _Dialog_Box.SetActive(true);
                 Dialog_With_Gate();
             }
         }
     }
 
    
 }
