Сбой интерфейса RecycleView

Question

Я делаю свой проект, который мне нужен для извлечения данных из FIREBASE, когда значение ссылки / дочернего элемента изменяется в RecycleView и CardView. В моем коде нет ошибок, но когда я пытаюсь войти в этот интерфейс, происходит сбой. Я приложу свою кодировку ниже, если все знают, в чем проблема, пожалуйста, скажите мне. Большое спасибо.
