Фриз кнопки android studio

Question

я новичок в программировании. Изучаю Java, android разработку. Недавно я начал писать простое приложение-викторину. Я столкнулся с проблемой которую никак не могу решить. Суть заключается в фризе, из которого нельзя выйти. Это происходит при нажатии на кнопку. Прикрепляю архив с проектом и видео фриза. Так-же этот фриз происходит только при умножении или делении и тд(6-16 лвла). https://drive.google.com/open?id=1ZJOlEmmpCHBzsil2bA55-U1O_9Oq-DPK https://drive.google.com/open?id=1ot_bdciwOnKeC4REXDC_jW7uvztJgAkC
