prefab movetowards correctly in editor and windows build but not webgl build

my game instantiates a prefab via button and it works fine in the editor and windows build but not the webgl build.

 using System.Collections;
 using System.Collections.Generic;
 using UnityEngine;
 
 public class FrogAI : MonoBehaviour
 {
     public Player player;
     private Vector2 position;
     private Vector2 target;
     private Vector2 target2 ;
     private Vector2 target3 ;
     public float speed;
     bool isRunning;
     bool counted;
 
     void Start()
     {
         isRunning=true;
         player = GameObject.FindGameObjectWithTag("player").GetComponent<Player>();
         target = new Vector2(Random.Range(-3.5f,-2.5f),Random.Range(0f,-1.5f));
         target2 = new Vector2(Random.Range(.5f,1f),Random.Range(-2.25f,-3f));
         target3 = new Vector2(6f,Random.Range(-2f,-3f));
       position = gameObject.transform.position;  
     }
 
     // Update is called once per frame
     void Update()
     {
        Debug.Log(this.transform.position.x +" "+ this.transform.position.y);
         
         if(isRunning&&player.currentMultiplyer<player.maxMultiplyer){
             counted = true;
             player.currentMultiplyer+=player.bonusPerFrog;
             isRunning=false;
         }
         speed = player.speedInc;
         float step = speed*Time.deltaTime;
        transform.position = Vector2.MoveTowards(this.transform.position,target,step);
         
         if(Vector2.Distance(this.transform.position,target)<.01){
             target = target2;
         }
         if(Vector2.Distance(this.transform.position,target)<.001){
             target = target3;
         }
         
         
         if(Vector2.Distance(transform.position,target3)<0.1f){
             if(counted){
             player.currentMultiplyer-=player.bonusPerFrog;
             }
             Destroy(transform.root.gameObject);
             if(this.gameObject.name=="queenFrog(Clone)"){
                 player.frogs+=player.queenFrogValue;
             }else{
                 player.frogs++;
             }        
         }
     }
 
     public void spawnFrog(){
        
     }
 }
