Сервер разработки Django до вчерашнего дня работал нормально, используя mysql. Но сегодня я получаю ошибку AttributeError: 'bytes' object has no attribute 'encode'.
Я создал новый пустой экземпляр django, запустив django-admin startproject newProject. Он работает с 'ENGINE': 'django.db.backends.sqlite3'. Но выдает ту же ошибку, когда я изменяю ее на 'ENGINE': 'django.db.backends.mysql'
Спецификация системы:
os: manjaro linux
virtual environment python version: 3.6
Django version: 2.2
MariaDB version: 10.3.15-1
Не обновлял ни одного связанного пакета за последние 3 дня.

Как мне это исправить?
