После очистки интерфейса путем добавления большого количества свойств android:visibility="gone" и "invisible", здесь появляется сообщение «Ошибка: несоответствующий тег» в строке с последней по последнюю: </LinearLayout>.
Удаляя это, выдает ошибку еще в последней строке: </android.support.constraint.ConstraintLayout">
