Game Crashes when object gets near player

THIS POST IS NOW IRRELEVANT PLEASE CHECK MY NEWER ONE

I am making a horror game with next bots on VR (Quest/Quest2)

the player has 1 "Mixed" light on it and the bots use pathfinding AI with navmeshes and stuff but it seems that when the next bot gets within I'll say like 10 feet of the player and the player can see it and all the game just decides it wants to freeze and stop working!

It seems to happen before the player "Dies" but I'm not fully sure.

public class Kill : MonoBehaviour
{
    // Start is called before the first frame update

    public GameObject tes;
    public GameObject LocoToOff;
    public Vector3 SPOT;
    public GameObject SprintLoco;
    public GameObject Dead;
    public AudioSource audioSource;
    private bool Using;
    public GameObject Safe;
    public LocomotionControllery Loco;
    private bool ChillOutItsGoing;

    IEnumerator TurnOff()
    {
        ChillOutItsGoing = true;
        LocoToOff.SetActive(false);
        SprintLoco.SetActive(false);

        Dead.SetActive(true);


        Loco.Disabled = true;

        audioSource.Play();

        yield return new WaitForSeconds(3);


        //foreach (var pls in WallsNStuff)
        //{
        //    pls.SetActive(false);
        //}


        tes.transform.position = SPOT;


        //yield return new WaitForSeconds(0.05f);


        Loco.Disabled = false;

        Dead.SetActive(false);

        //foreach (var pls in WallsNStuff)
        //{
        //    pls.SetActive(true);
        //}

        Safe.SetActive(true);

        ChillOutItsGoing = false;
    }

    void OnTriggerEnter(Collider other)
    {
        if (other.gameObject.tag == "BOT")
        {
            if (ChillOutItsGoing == false)
            {
                Debug.Log(other.gameObject.name);
                Using = LocoToOff.active;
                StartCoroutine(TurnOff());
            }
        }
    }

}
