Question Attack Animation Freezing Every Other Animation

I'm trying to set up an attack animation for my game, just a small school project. I've never used unity and I'm not super familiar with it.

I've been following this video as a guide

However, i've found that when I have the transition for my attack animation from any state it freezes everything but when removed it works fine.

- video showing my issue.

here is my player combat script, if it helps.

Code (CSharp):

1. using UnityEngine;
2.  
3. public class playercombat : MonoBehaviour
4. {
5.     public Animator anim;
6.     public Transform attackpoint;
7.     public float attackrange = 0.5f;
8.     public LayerMask enemyLayers;
9.  
10.     // Update is called once per frame
11.     void Update()
12.     {
13.         if (Input.GetKeyDown(KeyCode.Space));
14.         {
15.             attack();
16.         }
17.     }
18.  
19.     void attack()
20.     {
21.         //play atk animation
22.         anim.SetTrigger("attack");
23.         // dectect enimies in range
24.         Collider2D[] hitEnemies = Physics2D.OverlapCircleAll(attackpoint.position, attackrange, enemyLayers);
25.         //apply damage
26.         foreach(Collider2D enemy in hitEnemies)
27.         {
28.             Debug.Log("Hit" + enemy.name);
29.         }
30.     }
31. }
