How can I spawn balls in every direction around a source (making a sphere) and then make the balls move away from that source?

I have a code that I put on my source and the ObjectToSpawn is a ball. Unity freezes when I click because something is wrong with my for loops. Also, the spheres all move in the same direction (instead of away from the source) when I don't use for loops.

 using System.Collections;
 using System.Collections.Generic;
 using System.ComponentModel.Design.Serialization;
 using UnityEngine;
 
 public class SpawnerSample : MonoBehaviour
 {
     public Rigidbody ObjectToSpawn;
     [SerializeField]
     float radius;
     void Update()
     {
         if(Input.GetMouseButton(0))
         {
             for(int angleY = 0; angleY <= 360; angleY += 45)
             {
                 for(int angleZ = 0; angleZ <= 360; angleY += 45)
                 {
                     Spawn(0, angleY, angleZ);
                 }
             }
         }
     }
 
     void Spawn(int angleX, int angleY, int angleZ)
     {
         Vector3 direction = Quaternion.Euler(0, angleY, angleZ) * Vector3.one;
         Vector3 spawnPosition = transform.position + direction * radius;
         Rigidbody Clone;
         Clone = Instantiate(ObjectToSpawn, spawnPosition, Quaternion.identity) as Rigidbody;
         Clone.velocity = direction.normalized;
     }
 }
