如何毫无例外地关闭不和谐的客户端连接（python3）

假设我有一个简单的分歧。客户端代码：

import os
import discord
from dotenv import load_dotenv
load_dotenv()
intents = discord.Intents.default()

TOKEN = os.getenv('DISCORD_TOKEN')
GUILD = os.getenv('DISCORD_GUILD')

client = discord.Client(intents=intents)

@client.event
async def on_ready():
    guild = None
    for guild in client.guilds:
        if guild.name == GUILD:
            break

    print(
        f'{client.user} is connected to guild {guild.name} (id: {guild.id})'
    )

client.run(TOKEN)

所以，当我停止代码时，我得到了一个异常：

Traceback (most recent call last):
  File "C:\Users\HP\AppData\Local\Programs\Python\Python39\lib\asyncio\proactor_events.py", line 116, in __del__
    self.close()
  File "C:\Users\HP\AppData\Local\Programs\Python\Python39\lib\asyncio\proactor_events.py", line 108, in close
    self._loop.call_soon(self._call_connection_lost, None)

    self._check_closed()
  File "C:\Users\HP\AppData\Local\Programs\Python\Python39\lib\asyncio\base_events.py", line 515, in _check_closed
    raise RuntimeError('Event loop is closed')
RuntimeError: Event loop is closed

Process finished with exit code 0

它不会以任何方式影响代码和功能，但它非常令人讨厌。那么我如何正确断开/关闭连接？
