[Python] Connecting aiogram and telethon

I am writing a telegram bot that needs to send some messages using the telethon client and some using aiogram. He makes a mistake that I don't understand

I ve tried this code:

bot = Bot(token=bot_token)
dp = Dispatcher()
client = TelegramClient("session", api_id, api_hash).start(bot_token=bot_token)


@dp.message(CommandStart())
async def start(message: types.Message):
await message.answer("text aiogram")
await client_send(message)


async def client_send(message: types.Message):
async with client:
await client.send_message(message.chat.id, "text telethon")


async def main():
await dp.start_polling(bot)

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


when the bot receives a message, I get this long traceback:

Cause exception while process update id=xxx by bot id=xxx
RuntimeError: The asyncio event loop must not change after connection (see the FAQ for details)
