Unity Freezes After Script and Has to be Terminated

This is a simple script for opening and closing a door within distance, If I aproach once the door opens, if I aproach and It is open it closes. But for some reason, when I get on contact witch the door's trigger, Unity Freezes at all, to never unfreezee, the only way to stop unity when it happens is by going on the Task Manager and terminating it then restarting the engine (Of course if I get near the doors it will happen again). Why is it happening?

Code (CSharp):

1. using System.Collections;
2. using System.Collections.Generic;
3. using UnityEngine;
4.  
5. public class Door : MonoBehaviour
6. {
7.     public GameObject door;
8.     private bool isClosed;
9.     private int colCount;
10.  
11.     void Start ()
12.     {
13.         isClosed = false;
14.         colCount = 0;
15.     }
16.  
17.     void OnTriggerEnter (Collider col)
18.     {
19.         if (col.gameObject.tag == "Player" )
20.         {
21.             if (colCount % 2 == 0)
22.             {
23.                 while (door.transform.eulerAngles.z <= 89)
24.                 {
25.                     door.transform.eulerAngles += new Vector3 (0,0, 1 * Time.deltaTime);
26.                 }
27.             }
28.             else if (colCount % 2 == 1)
29.             {
30.                 while (door.transform.eulerAngles.z >= 1)
31.                 {
32.                     door.transform.eulerAngles -= new Vector3 (0,0, 1 * Time.deltaTime);
33.                 }
34.             }  
35.         }
36.     }
37. }
38.

Its definitely the while loops. Unfortunately, the exact reason why isn't hitting me.

 

Try this to see your values
