Possible Infinite Loop Freezing Game

I t$$anonymous$$nk t$$anonymous$$s script "Card" is freezing my game every time I $$anonymous$$t play by getting stuck in an infinite loop. I can't figure out why t$$anonymous$$s is the case (if it is) as it seems like the loop should close. Maybe I just need a fresh set of eyes to look at it since I have been staring at it too long.

using System.Collections; using System.Collections.Generic; using UnityEngine;

public class Card : MonoBehaviour { public float cardValue; public string suit;

 public GameObject cardAvailability;

 void Start()
 {
     Debug.Log("Instantiating Card");

     cardAvailability = GameObject.FindGameObjectWithTag("CardAvailability");
     bool searc$$anonymous$$ng = true;

     w$$anonymous$$le (searc$$anonymous$$ng)
     {
         cardValue = (int)(Random.Range(2, 15));
         float randomSuit = (int)(Random.Range(0, 4));
         
         if (cardAvailability.GetComponent<CardAvailability>().CheckCard(suit, cardValue) == true)
         {
             cardAvailability.GetComponent<CardAvailability>().disableCard(suit, cardValue);
             searc$$anonymous$$ng = false;
         }
     }

     Debug.Log("Card Instantiated: " + cardValue + suit);
 }

 public override string ToString()
 {
     string output = "";

     switch (cardValue)
     {
         case 2:
             output += "Two";
             break;
         case 3:
             output += "Three";
             break;
         case 4:
             output += "Four";
             break;
         case 5:
             output += "Five";
             break;
         case 6:
             output += "Six";
             break;
         case 7:
             output += "Seven";
             break;
         case 8:
             output += "Eight";
             break;
         case 9:
             output += "Nine";
             break;
         case 10:
             output += "Ten";
             break;
         case 11:
             output += "Jack";
             break;
         case 12:
             output += "Queen";
             break;
         case 13:
             output += "King";
             break;
         case 14:
             output += "Ace";
             break;
         default:

             break;
