Как сделать sys.exit () с asyncio Python 3.8 + / Windows 10+ без исключений?

Я хочу написать такую ​​программу asyncio, которая существует для некоторых проблем. Я должен работать, но он генерирует ужасный вывод вместо чистого выхода. Как сделать sys.exit() без таких безобразных исключений?

Вот код: 

import asyncio
import sys


async def main():
    sys.exit()


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

Результат: 

C:\root\Python38\python.exe C:/Users/x/PycharmProjects/dptr-monitoring-v2/sandbox/python/s06_asyncio/s02_exit.py
