make sure there is no overlap when re-enabling objects

Question

I am disabling objects when shot, but the problem is I don't know how to check if there's something is in the way (player or enemies etc) when re-enabling the objects. Right now the objects get re-enabled even if the player is in the way and that's causing issues. Here's my code:

 public class BreakingBlocks : MonoBehaviour
 {
     public float DestroyTimer = 0F;     /// Wait time before destoying
     public float RespawnTimer = 1.5F;   /// wait time before respawning
     public bool DisableRespawning = false; /// Disable respawning
 
     void OnTriggerEnter2D(Collider2D collider)
     {
         if (collider.gameObject.tag == "BreakBlocks")
         {
             Invoke("RandomCube", DestroyTimer);
         }
     }
     void RandomCube()
     {
         gameObject.SetActive(false);
         if (DisableRespawning)
         {
             return;
         }
            Invoke("SpawnCube", RespawnTimer);
     }
     void SpawnCube() // re-enable objects
     {
         gameObject.SetActive(true);
     }

i’d change the gameobjects tag before disabling, then on setactive you first check if the collider intersects with anything, like player or what ever you dont want to be overlapping with. => for example a bunch of grass is ok to be overlapped with, but not a player/enemy so after you setactive(true) you can check with this:

 GameObject[] AllCharacters;
 bool intersects = false;
 var bb = GetComponent<Collider>().bounds; 
 
 for(int i = 0; i<AllCharacters.Length;i++){
   if(bb.Intersects(AllCharacters[i].GetComponent<Collider>().bounds)){
     intersects = true;
     return;
     }
 }
 
 if(intersects){
   //do something
   intersects = false;
 }
 
 // Second Solution
 
 void OnCollisionStay/OnTriggerStay(Collision / Collider col){
   if(col.transform.tag == "Player" || col.transform.tag == "Enemy"){
     //do something
     }
 }
