How can i make enum choice to not pause the game ?

 using System.Collections;
 using System.Collections.Generic;
 using UnityEngine;
 
 public class Animations : MonoBehaviour
 {
     public enum AnimatorStates
     {
         WALK, RUN, IDLE
     }
 
     public AnimatorStates animatorStates;
     private Animator _anim;
 
     void Awake()
     {
         _anim = GetComponent<Animator>();
     }
 
     private void Start()
     {
 
     }
 
     public void PlayState(AnimatorStates state)
     {
         string animName = string.Empty;
         switch (state)
         {
             case AnimatorStates.WALK:
                 animName = "Walk";
                 break;
             case AnimatorStates.RUN:
                 animName = "Run";
                 break;
         }
         if (_anim == null)
             _anim = GetComponent<Animator>();
 
         _anim.Play(animName);
     }
 
     void Update()
     {
         PlayState(animatorStates);
     }
 }
 

While the game is running and i click on the animatorStates in the Inspector while the game is running the game is pause until i select a state. Is there any way to make that the game will keep running when i click on the enum menu in the inspector the animatorStates ?
