RuntimeError: Timeout context manager should be used inside a task - aiogram

Пишу тестового бота, чтобы разобраться с aiogram. При запуске бота сразу появляется ошибка Timeout context manager should be used inside a task при вызове dp.start_polling(bot)

Код программы main.py:

bot = Bot(config.BOT_KEY)
dp = Dispatcher(bot)
setup_handlers(dp)

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

if __name__ == "__main__":
    try:
        asyncio.run(main())
    except Exception as ex:
        log.error(ex)

handlers.py:

def setup_handlers(dp: Dispatcher):
    dp.register_message_handler(_on_start, Command("start"))
    dp.register_message_handler(_get_info, Command("info"))


async def _on_start(message: types.Message): 
    await message.answer(messages.hello_message)


async def _get_info(message: types.Message):
    await message.answer(messages.info)

Используемые версии:

Python     3.11.6
aiogram    2.9
aiohttp    3.9.1
aiosignal  1.3.1
