Instantiated Prefab not calling Start() nor Awake()

So when I instantiate a prefab, it looks for a gameObject with the tag of "Inventory". However, it doesn't work properly. What DOES work is when I instantiate it, pause UnityEditor and then un pause the game and then it works. Here is my script.

 public class FireTurnOn : MonoBehaviour {
 
     public GameObject Canvas;
 
     void Awake()
     {
         foreach (RectTransform go in GameObject.FindObjectsOfType<RectTransform>())
         {
             //print(go.tag);
             if (go.tag == "Inventory")
             {
 
                 Canvas = go.gameObject;
             }
         }
     }
     
     void Update ()
     {
         if (Canvas == null)
         {
             Awake();
         }
     }
 
     void Interact ()
     {
 
         if (Canvas == null)
         {
             foreach (RectTransform go in GameObject.FindObjectsOfType<RectTransform>())
             {
                 //print(go.tag);
                 if (go.tag == "Inventory")
                 {
                     print("Found the canvas");
                     Canvas = go.gameObject;
                 }
             }
         }
 
         bool hasWood = Canvas.GetComponent<Inventory>().FindWoodSlot() != null;
 
         if (hasWood)
         {
             GameObject woodSlot = Canvas.GetComponent<Inventory>().FindWoodSlot();
 
             woodSlot.GetComponent<UnityEngine.UI.Image>().sprite = Canvas.GetComponent<Inventory>().Empty;
             transform.GetC$$anonymous$$ld(0).gameObject.SetActive(true);
             transform.GetC$$anonymous$$ld(0).gameObject.GetComponent<FireDestroyer>().Start();
         }
 
     }
 
 }
