Написал бота для скачивание видео с ютуба на aiogram, но он выдает ошибку

Использую последнюю версию aiogram
код:

import asyncio
import os
import config
from aiogram import Bot, Dispatcher, types, filters
from pytube import YouTube

async def main():
    bot = Bot(token=config.BOT_TOKEN)
    dp = Dispatcher()
    dp.bot = bot

    @dp.message(filters.Command("download"))
    async def handle_download(message: types.Message):
        try:
            video_url = message.text.split()[1]
            save_path = "./"
            await message.answer('Видео в обработке')

            yt = YouTube(video_url)
            stream = yt.streams.filter(resolution='720p', progressive=True).first()
            video_file = stream.download(output_path=save_path)

            await message.answer(f"Видео '{yt.title}' успешно загружено!")

            with open(video_file, 'rb') as video:
                await bot.send_video(message.chat.id, video)

            os.remove(video_file)

            await message.answer("Видео успешно отправлено и удалено с сервера.")
        except Exception as e:
            await message.answer(f"Произошла ошибка: {str(e)}")
    await dp.start_polling()

if __name__ == '__main__':
asyncio.run(main())

Ошибка:
