script wont re activate object when my conditions are met

What i am trying to do is set whether or not an object should be simulateded. If a player is within 100 units it should render and simulate the rigidbody, if not then it should disable the game object. However when i try to reactivate it will not work.

 @HideInInspector
 var PO : GameObject;
 @HideInInspector
 var D: Vector3;
 @HideInInspector
 var rendered : boolean = true;
 @HideInInspector
 var CT : float;
 
 var RenderDistance : float = 100;
 var CheckTime : float = 2;
 
 function Awake()
 {
     PO = GameObject.FindGameObjectWithTag("Player");    
 }
 
 function Update () 
 {
     
     CT += Time.deltaTime;
     if(CT >= CheckTime)
     {
         D = GameObject.FindGameObjectWithTag("DistanceProbe").GetComponent("PlayerDistanceMonitor").PlayerPosition;
         
         if(Vector3.Distance(transform.position, D) > RenderDistance)
         {
             gameObject.active = false;
         }
         
         if(Vector3.Distance(transform.position, D) < RenderDistance)
         {
             Debug.LogError("This is still working");
             gameObject.active = true; //however this isnt
             
         }
     }
     
 }

I have tried this also by just disabling the physics constraints and renderer. But when it reactivates the mesh renderer does not activate also... Any ideas?
