Асинхронные функции: ошибка "There is no current event loop in thread 'MainThread'"

Когда я еще раз вызываю функцию, внутри которой асинхронная функция, я получаю ошибку:There is no current event loop in thread 'MainThread'

Как избежать данную ошибку при повторном вызове функции? Я нашел, что я получаю ошибку, потому что event loop закрывается после первого запуска функции. Мне следует использовать что-то вместо asyncio.run или как мне сделать чтобы eventloop можно было использовать повторно
