Django переименование класса casued AttributeError: у объекта 'str' нет атрибута '_meta'

Question

Как я могу решить эту проблему, я переименовал сквозной класс Model и теперь получаю следующую ошибку при попытке миграции:

(django_env) UKC02TQH6UHV22:pcc_django rki23$ python manage.py migrate

Что мне нужно сделать, чтобы это исправить, пожалуйста?

Это файл миграции, который вызывает проблему. Смена имени была для поля «многие ко многим».
