Animation only Playing for 7 Frames

I have this script as my animation player: using UnityEngine;

 public class animationPlayer : MonoBehaviour {
 
     public Animation allAnim;
 
     void Update () {
         if (Input.GetKeyDown("w") || Input.GetKeyDown("d") || Input.GetKeyDown("s") || Input.GetKeyDown("a"))
         {
             GetComponent<Animation>().Play("walk");
         }
         else
         {
             GetComponent<Animation>().Stop("walk");
         }
 
         if (!Input.GetKeyDown("w") || Input.GetKeyDown("d") || Input.GetKeyDown("s") || Input.GetKeyDown("a") || Input.GetKeyDown(KeyCode.LeftShift) || Input.GetKeyDown("space"))
         {
             GetComponent<Animation>().Play("idle");
         }
         else
         {
             GetComponent<Animation>().Stop("idle");
         }
     }
 }
 

But whenever I go into play mode, the walk animation only plays for 7 frames when I press w, a, s or d keys and it is 110 frames long (I know that is long for a walk animation). Can anyone help? I have a video here if it will help: https://youtu.be/OqTo_aPQ0MQ
