Результат

Макет отображается неправильно.
Что я могу сделать для правильной работы?

Если я использую RelativeLayout, все работает.
Что не так? Я не понимаю.

Android Studio предоставляет вам понятное сообщение об ошибке в вашем ImageView :

Итак, добавьте вертикальные ограничения.

 app:layout_constraintTop_toTopOf="parent"
app:layout_constraintBottom_toBottomOf="parent"
