Problema tentando criar um bot para Discord

Olá, estava tentando criar um bot para discord para treinar meus conhecimentos de NLP em uma interação com usuários reais. Como tudo tem um começo estava escrevendo as primeiras linhas de código quando me deparei com esse erro:

C:\Python38\python.exe C:/Users/evers/PycharmProjects/ValForDiscord/main.py
Traceback (most recent call last):
  File "C:\Python38\lib\site-packages\discord\http.py", line 291, in static_login
    data = await self.request(Route('GET', '/users/@me'))
  File "C:\Python38\lib\site-packages\discord\http.py", line 245, in request
    raise HTTPException(r, data)
discord.errors.HTTPException: 401 Unauthorized (error code: 0): 401: Unauthorized

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

Traceback (most recent call last):
  File "C:/Users/evers/PycharmProjects/ValForDiscord/main.py", line 15, in <module>
    client.run(TOKEN)

    raise RuntimeError('Event loop is closed')
RuntimeError: Event loop is closed

Meu código está assim:

import os

import discord
from dotenv import load_dotenv

load_dotenv()
TOKEN = os.getenv('DISCORD_TOKEN')

client = discord.Client()

@client.event
async def on_ready():
    print(f'{client.user} has connected to Discord!')

client.run(TOKEN)

Verifiquei e o Token estava correto. Ao pesquisar no Stack Overflow, descobri que o problema seria no async, mas como não tenho nenhum conhecimento nesse elemento da linguagem, não consegui resolver meu problema. Alguém poderia me explicar o que aconteceu e como eu poderia resolver?
