I wanted to use cog but it doesn’t work, the same error appears all the time, I tried different ways of implementation, delete cache and the like, but nothing.

main.py:

import discord
from discord.ext import commands

import os

intents = discord.Intents.all()
client = commands.Bot(command_prefix="!", intents=intents)


@client.event
async def setup_hook():
    for filename in os.listdir('./Cogs'):
        if filename.endswith('.py'):
            await client.load_extension(f'Cogs.{filename[:-3]}')
            print(f"Loaded Cog: {filename[:-3]}")
        else:
            print(f"Skipped loading Cog. ({filename[:-3]})")

Cogs/Hello.py

import discord
from discord.ext import commands

class Hello(commands.Cog):
    def __init__(self, client):
        self.client = client

    @commands.command()
    async def hello(self, ctx):
        await ctx.send("Hello There!")

    @commands.Cog.listener()
    async def on_ready(self):
        print(f"We're live! Logged in as {self.client.user.name}")

async def setup(client):
    await client.add_cog(Hello(client))

Error:
