Всякий раз, когда я go для python manage.py runserver, эта ошибка отображается максимальное время -

Эту ошибку можно устранить с помощью сочетаний клавиш CTRL + C / CTRL + Z ie, нарушив команду runserver, а затем снова перейдя к той же команде PYHTON MANAGE.PY RUNSERVER, иногда удаляет ошибку, но ИНИЦИАЛЬНО.

В наши дни эта ошибка чаще встречается у меня для каждой команды runserver, и она требует многократного прерывания ie после многих попыток разорвать команду runserver и затем снова запустить сервер, чтобы удалить ошибку.

Эта ошибка чаще всего отображается для DJANGO Rest API. Я получаю эту ошибку с любым типом API-кода для простого или даже для сложного. Я пытался найти его, но это не устраняет ошибку.

Спасибо
