При добавлении нового виджета в kivy приложение перестает работать

Недавно начал разбираться с kivy и столкнулся с такой проблемой. Приложение работает при запуске на ПК, но после сборки через buildozer оно не запускается. Выводил логи через logcat, какой-то определенной ошибки нет. В процессе разбирательства заметил, что подобная ошибка возникает если добавить любой дополнительный Layout в Container (будь то box, grid или scroll view). Пытался дублировать уже работающие элементы, но ситуация не меняется. Может быть в kivy есть какое-то ограничение по количеству виджетов?
