[CLOSED] renderer.enabled is set to true but does not show

I have this script which disables the renderer and collider of an object called "panel".

 public class PanelDisable : MonoBehaviour {
 
    private float timer;
    public int disable_time;
    public bool disabled;
 
    void Start() {
       disabled = false;
       disable_time = 5;
    }
 
    void Update() {
       if(disabled)
       {
           timer += Time.deltaTime;
           print("Disabled");
           rendered.enabled = false;
           collider.enabled = false;
       }
 
       if(timer >= disable_time)
       {
           print("enable renderer");
           renderer.enabled = true;
           collider.enabled = true;
           timer = 0;
           disabled = false;
       }
    }
 }

the boolean "disabled" is set to true by a bomb enemy (another gameobject), that explodes after 3 seconds upon spawning, and disables the nearest panel gameobject in this way:

 if(intTime == 3)
 {
     FindNearestPanel().GetComponent<PanelDisable>().disabled = true;
     Destroy(gameObject);
 }

Well, the panel's collider and renderer are set to true when the bomb enemy explodes. However, both collider and renderer doesn't come back after 5 seconds. Everything I tried to print appears in the console, and if I check the inspector, the objects' collider and renderer are actually checked. BUT WHY IS IT THAT THEY DON'T SHOW :( It frustrates me, as I can't see what I'm doing wrong. Have I forgotten something? :(
