Ошибка при обновлении и удалении миграции. а надстройка работает?

Я делаю проект в курсе udemy о .NET 6. Во всяком случае, мне приходит в голову, что когда я запускаю проект «миграция добавить», все идет отлично. Однако при выполнении удаления или обновления базы данных появляется следующее исключение. System.InvalidOperationException: The ConnectionString property has not been initialized.

Ну ни один не работал. Я оставлю GitHub и некоторый код проекта на случай, если это поможет. Я также оставлю команду миграции, используя --verbose. Проект на GitHub. Еще одна деталь в том, что я скачал проект профессора в этом же коммите, и его команды работают. Проверил все через сайт сравнения, проект тот же. Я также тестировал с использованием тех же версий зависимостей, но тоже ничего.

CLI с использованием dotnet ef migrations remove --verbose

Я уже обновил все зависимости проекта и следил за некоторыми решениями, которые я нашел здесь, такими как это , и другими решениями в документации, такими как это.
