поэтому не сосредотачивайтесь на файлах json или csv, когда я запускаю свой основной код, я вхожу в систему, и он успешно входит в систему, я жестко запрограммировал файл csv на данный момент для удобства, поэтому, когда я запускаю код, он успешно открывает журнал в графическом интерфейсе, после успешного входа в систему окно уничтожается, и я ожидаю, что после него запустится код, но возникает эта ошибка

_tkinter.TclError: невозможно вызвать команду «tk»: приложение было уничтожено

Я беспомощен сейчас, примерно через 3 часа я не понимаю, почему это срабатывает, потому что типа графический интерфейс создан. Также я пытался его отладить, добавлял операторы печати и даже использовал .protocall(), но ничего не помогает, даже в чате gpt говорит, что с вашим кодом все в порядке, а проблема, Эми, кроется в самой библиотеке, он предлагает мне пересобрать все приложение. Я новичок, и восстановление его звучит слишком скучно и беспокойно, поэтому, если возможно, кто-нибудь может решить мою проблему. Раньше у меня был интерфейс входа и входа в систему, которые могли переключаться между собой, но я отказался от него в надежде устранить ошибку
