Index out of bound when trying to select a character

I am having a small error here while trying to access a car in the character selection script I did whatever i could but could not solve it can anyone please help me using System.Collections; using System.Collections.Generic; using UnityEngine; using UnityEngine.SceneManagement;

public class CarSelector : MonoBehaviour { //Made gameobject of the character list private GameObject[] characterList; private int index;

 private void Start()
 {
     index = PlayerPrefs.GetInt("Character Selection");
     //added count to the child objects of the character list
     characterList = new GameObject[transform.childCount];

     //got the first character in the list
     for (int i = 0; i < transform.childCount; i++)
     {
         characterList[i] = transform.GetChild(i).gameObject;
     }
     
     //disabled the inactive child characters
     foreach(GameObject go in characterList)
             go.SetActive(false);
     //toggle on the first character
     if (characterList[index])
         characterList[index].SetActive(true);
     
 }
