«Исключение: ScrollView принимает только один виджет» после сборки с помощью PyInstller

Question

Мне нужна помощь. Я получаю исключение "Исключение: ScrollView принимает только один виджет" после создания приложения KIVY с PyInstaller. Если я запускаю его из IDE или вызываю основной из командной строки, он запускается без ошибок.

Это вывод консоли:

...

Я не могу понять, где проблема, потому что перед сборкой приложения оно работает, как и ожидалось.
