при добавлений Retrofit в NestedScrollView в виде списка RecycleView выходит ошибка

список очень долго прогружается и зависает а после вылетает

без NestedScrollView и CollapsingToolbarLayout работает хорошо что делать

вот код как работает приложение много раз расходует память(не знаю как правильно написать)

ошибка во вкладке ran код ошибки
