SOLVED
Im working on a project im doing for a theater, and we have an animation that plays after the shoot cooldown is over, however after it instantiates the object it freezes my entire unity, this never happened before i made the code to incorporate the new coroutine and animation, so idk exactly what is causing it.

using System.Collections;
using UnityEngine;

public class CerberusHead : MonoBehaviour
{
    public float throwForce = 10f;
    public float projectileSpeed = 5f; // Adjust the speed as needed
    public Transform highSpawnPoint; // Spawn point for high projectiles
    public Transform lowSpawnPoint; // Spawn point for low projectiles
    public Transform backWall;
    public GameObject cerberusHead;
    public float attackTimer = 7f;
    public float attackTimerWithAnimation = 14f;
    public SpriteRenderer topHeadRenderer;
    public SpriteRenderer bottomHeadRender;
    public RuntimeAnimatorController topHeadController;
    public RuntimeAnimatorController bottomHeadController;
    public float hitPoints = 10;
    public Animator TopHead;
    public Animator BottomHead;
    private bool throwHigh;
    public bool canAttack;

    void Start()
    {
        // Start the coroutine for periodic attacks
        canAttack = true;
        StartCoroutine(AttackPeriodically());
    }

    IEnumerator AttackPeriodically()
    {
        while (true)
        {
            if (canAttack)
            {
                // Wait for seconds before each attack
                yield return new WaitForSeconds(attackTimer);

                // Perform the attack
                Attack();
            }
        }
    }

    void Attack()
    {
        // Determine if the head should throw high or low
         throwHigh = Random.Range(0f, 1f) > 0.5f;
        if (throwHigh)
        {
            Debug.Log("1");
            TopHead.Play("TopCharging");
        }

        if (!throwHigh)
        {
            Debug.Log("2");
            BottomHead.Play("BottomCharge");
        }
        StartCoroutine(WaitForAnimation());
        GameObject projectile = Instantiate(cerberusHead, throwHigh ? highSpawnPoint.position : lowSpawnPoint.position,
            Quaternion.identity);
        CerberusProjectile projObject = projectile.GetComponent<CerberusProjectile>();
        Animator animator = projObject.GetComponent<Animator>();
        if (projectile.transform.position == highSpawnPoint.transform.position)
        {
            projObject.topOrDown = true;
            topHeadRenderer.enabled = false;
            projObject.parentRenderer = topHeadRenderer;
            animator.runtimeAnimatorController = topHeadController;
        }
        else
        {
            projObject.topOrDown = false;
            bottomHeadRender.enabled = false;
            projObject.parentRenderer = bottomHeadRender;
            animator.runtimeAnimatorController = bottomHeadController;
        }
        projObject.backWall = backWall;
        projObject.head = this.GetComponent<CerberusHead>();
        Rigidbody2D projectileRb = projectile.GetComponent<Rigidbody2D>();
        projectileRb.velocity = Vector2.left * throwForce * projectileSpeed; // Adjust speed
        canAttack = false;
        attackTimer = attackTimerWithAnimation;
    }

    IEnumerator WaitForAnimation()
    {
        yield return new WaitForSeconds(6.5f);
    }

}

Any idea?
