мой XML-файл. В предварительном просмотре есть две ошибки: «Не удалось загрузить AppCompat ActionBar с неизвестной ошибкой» и «Не удалось создать более одного класса». Как только я могу запустить приложение. Но приложение вылетает и в Logcat ошибок не отображается.

Это мой предварительный снимок экрана
