Right guys struggling here! new to code... My first object (power up) is being destroyed but no power function is being generated, second object and there after works perfectly. PLEASE HELP

 using System.Collections;
 using System.Collections.Generic;
 using UnityEngine;
 
 public class PowerUps : MonoBehaviour
 {
     public bool doublePoints;
     public float powerupLength;
     private PowerupManager thePowerupManager;
 
     // Start is called before the first frame update
     void Start()
     {
         thePowerupManager  = FindObjectOfType<PowerupManager>();
     }
 
     void Awake()
     {
         doublePoints = true;
     }
 
     void OnTriggerEnter2D(Collider2D other)
     {
         if(other.name == "Player")
         {
             thePowerupManager.ActivatePowerup(doublePoints, powerupLength);
             gameObject.SetActive(false);
         }
     }
 }
