Ошибка фрагмента при использовании Firebase для Android

Question

Я создаю нижнюю навигацию для моего приложения android. У меня есть логин пользователя с использованием Firebase и переход на первый экран (домашний фрагмент). Этот фрагмент читает файл JSON и отображает информацию, которая работает нормально.

Проблема: Когда вы нажимаете, чтобы переключиться на фрагмент профиля, приложение вылетает и выдает фатальную ошибку, а я не знаю, как это исправить , Я относительно новичок в Android и пробовал много разных "решений", но безуспешно. Ниже приведены мои фрагменты и основная деятельность.

MainActivity. java

public class MainActivity extends AppCompatActivity implements BottomNavigationView.OnNavigationItemSelectedListener {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        loadFragment(new HomeFragment());

        //getting bottom navigation view and attaching the listener
        BottomNavigationView navigation = findViewById(R.id.navigation);
        navigation.setOnNavigationItemSelectedListener(this);
    }
    private boolean loadFragment(Fragment fragment) {
        //switching fragment
        if (fragment != null) {
            getSupportFragmentManager()
                    .beginTransaction()
                    .replace(R.id.fragment_container, fragment)
                    .commit();
            return true;
        }
        return false;
    }

    @Override
    public boolean onNavigationItemSelected(@NonNull MenuItem item) {
        Fragment fragment = null;

        switch (item.getItemId()) {
            case R.id.navigation_home:
                fragment = new HomeFragment();
                break;

            case R.id.navigation_dashboard:
                fragment = new DashboardFragment();
                break;

            case R.id.navigation_profile:
                fragment = new ProfileFragment();
