При запуски Телеграм бота ошибка - ERROR:aiogram.dispatcher.dispatcher:Cause exception while getting updates

Здорова всем. Решил научится разбираться в bot_telegram выбрал библиотеку (aiogram) для создания бота.

При использовании Python 3.7 вроде как работало но пришлось перейти на Python 3.8 одна часть функционала бота не работала на Python 3.7.

Anaconda (version 1.7.2)
Python (version 3.8.5)

Вывод с консоля.

P.s Нет я не взялся за реальный проект, это всего лишь личная инициатива.
