My character has broken animations

So i trie to make a attack combo system, here’s my script:-
using UnityEngine;

public class ComboAttackSystem : MonoBehaviour
{
int comboCounter;
public float cooldowTime = 0.1f;
float lastClicked;
float lastComboEnd;
public bool isAttacking;

[SerializeField] Weapon currentWeapon;
Animator animator;

private void Start()
{
    animator = GetComponent<Animator>(); 
}

private void Update()
{
    if( currentWeapon != null ) { Attack(currentWeapon.weaponName); }
}

void Attack(string weapon)
{
    if (Input.GetButtonDown("Fire1") && Time.time - lastClicked > cooldowTime)
    {
        isAttacking = true;

        comboCounter++;
        comboCounter = Mathf.Clamp(comboCounter, 0, currentWeapon.comboLength);

        for (int i = 0; i < comboCounter; i++)
        {
            if (i == 0)
            {
                if (comboCounter == 1 && animator.GetCurrentAnimatorStateInfo(1).IsTag("Movement"))
                {
                    animator.SetBool("AttackStart", true);
                    animator.SetBool(weapon + "Attack" + (i + 1), true);
                    lastClicked = Time.time;
                }
            }
            else
            {
                if (comboCounter >= (i + 1) && animator.GetCurrentAnimatorStateInfo(1).IsName(weapon + "Attack" + i))
                {
                    animator.SetBool(weapon + "Attack" + (i + 1), true);
                    animator.SetBool(weapon + "Attack" + (i), true);
                    lastClicked = Time.time;
                }
            }
        }
    }

    isAttacking = false;

    for (int i = 0; i < currentWeapon.comboLength; i++)
    {
        if (animator.GetCurrentAnimatorStateInfo(1).normalizedTime > 0.9f && animator.GetCurrentAnimatorStateInfo(1).IsName(weapon + "Attack" + (i + 1)))
        {
            comboCounter = 0;
            lastComboEnd = Time.time;
            animator.SetBool(weapon + "Attack" + (i + 1), false);
            animator.SetBool("AttackStart", false);
        }
    }
}

}
I get this error:
‘Player’ AnimationEvent ‘Hit’ on animation ‘2Hand-Sword-Attack7’ has no receiver! Are you missing a component?

and what my character is doing is that it play the first animation incompletely then jumps to 2nd and keeps playing that transtition until i press my mouse the 3rd time
