привязка данных с ошибкой фрагмента не может найти класс BindingImpl

Я часами боролся с этой ошибкой и перепробовал большинство найденных решений, но безуспешно

я убедился в

• Макет — это самый внешний тег
• включена привязка данных
• орфографические ошибки в xml
• установить модель представления в классе фрагмента
• и, конечно, аннулировать кеш и перезапустить

import com.linguistic.linguistic.databinding.FragmentAddNewConversationBindingImpl; ^ symbol: class FragmentAddNewConversationBindingImpl

Эта ошибка появляется только тогда, когда я использую модель представления в вызове xml. Мой xml: вы найдете меня, используя viewModel в первом переключателе
