Use pycord to make a music bot-CodePudding

My English is not good, I am still a newcomer, please forgive me if the question is not good. I'm using PyCord 2.3.2 to make a discord music robot. Currently, I only do the join command. Although I can join the channel, it throws an error.

Ignoring exception in command join:
Traceback (most recent call last):

The above exception was the direct cause of the following exception:

I tried to find the problem according to the error, but there is no good solution, hope to find a solution here.

this is my program Cogs:

import discord
from discord.ext import commands,tasks
import os
import youtube_dl
import asyncio
from definition.Classes import Cog_Extension

class Music(Cog_Extension):
    @commands.command(name='join', help='Tells the bot to join the voice channel')
    async def join(self,ctx):
        if not ctx.message.author.voice:
            await ctx.send("{} is not connected to a voice channel".format(ctx.message.author.name))
            return
        else:
            channel = ctx.message.author.voice.channel
        await channel.connect()
def setup(bot):
    bot.add_cog(Music(bot))

Bot:

import discord
import asyncio
from discord.ext import commands
import os
import json

with open("config.json" , "r" ,encoding="utf8") as configFiles:  
    config = json.load(configFiles)

intents = discord.Intents.all()
bot = commands.Bot(command_prefix=config["command_prefix"], intents=intents)

@bot.event
async def on_ready():
    os.system('clear')
    print("-"*15)
    print("
