Python code won't run, how to fix?

Question

Python

The bot started and everything was fine, but after adding intents to the bot, it started to give an error. How to fix?

import discord
from discord.ext import commands
bot = commands.Bot(command_prefix='.', intents=discord.Intents.all())

@bot.event
async def on_ready():
    print('Бот запущен')
token = open('token.txt', 'r').readline()
bot.run(token)

Mistake:

Traceback (most recent call last):
