Why is my Unity Game crashing whenever Time Left is close to 0?

So, currently, in my game, I'm trying to make a Game Manager that does all of the background management and running. Currently, all it does it make sure that some variables are met, and then spawn in a new character and run their AI so that they can fulfill the rest of their tasks. The code looks like this:

public GameObject Person;

 public Transform Spawn1;
 public Transform Spawn2;

 public int PlayersInStore;

 public float TimeLeft = 5;

 public bool Ready = false;


 // Start is called before the first frame update
 void Start()
 {
     TimeLeft = Random.Range(5.0f, 15.0f);
 }

 // Update is called once per frame
 void Update()
 {

     if(TimeLeft > 0.0f)
     {
         TimeLeft -= Time.deltaTime;
     }
     if (TimeLeft <= 0.0f)
     {
         Ready = true;
     }
     if (PlayersInStore < 5 && Ready == true)
     {
         SendInPlayer();
         Ready = false;
     }
 }

 public void SendInPlayer()
 {
     PlayersInStore = PlayersInStore + 1;

     int WhichSpawn = Random.Range(1, 3);
     Transform SpawnPoint = Spawn1;
     Transform FaceTowards = Spawn2;
     
     if(WhichSpawn == 1)
     {
         SpawnPoint = Spawn1;
         FaceTowards = Spawn2;
     }
     if (WhichSpawn != 1)
     {
         SpawnPoint = Spawn2;
         FaceTowards = Spawn1;
     }


     GameObject Player = Instantiate(Person, new Vector2 (SpawnPoint.position.x, SpawnPoint.position.y), Quaternion.identity);
     Player.SetActive(true);

     TimeLeft = Random.Range(5.0f, 15.0f);

     Player.GetComponent<PlayerAI>().SpawnedIn();
 }

The problem is that every time I run my code, whenever Time Left becomes really low (around 0.02f) it will crash Unity, nothing in the engine will be interactable and I can't stop running the game. The only way to fix it is to go into Task Manager and Force Shutdown Unity, then restart it. I don't know what the problem is, I think it may have to do with the if statements in the Update() function, but I have no clue and I don't want to have to keep restarting and crashing Unity when I could just come here and see if anyone knows how to fix it.
