Hilt can not cast ContextImpl to Application

  android, android-context, dagger-hilt, viewmodel

I use Hilt and recently had a strange problem. For a limited number of devices, I encounter the following error.

*dagger.hilt.android.internal.modules.ApplicationContextModule.provideApplication
ApplicationContextModule.java, line 45
java.lang.ClassCastException: android.app.ContextImpl cannot be cast to 
android.app.Application*

ApplicationContextModule generated by Hilt:

/** Provides a binding for an Android BinderFragment Context. */
@Module
@InstallIn(ApplicationComponent.class)
public final class ApplicationContextModule {
  private final Context applicationContext;

  public ApplicationContextModule(Context applicationContext) {
    this.applicationContext = applicationContext;
  }

  @Provides
  @ApplicationContext
  Context provideContext() {
    return applicationContext;
  }

  @Provides
  Application provideApplication() {
    return (Application) applicationContext.getApplicationContext();
  }
}

NOTICE: ApplicationContextModule was generated by Hilt

@HiltAndroidApp
class MyApp : Application(), Configuration.Provider {
   ...
}

What I am doing is just create an instance of RootWarninginViewModel (which is annotated with @ViewModelInject)

class RootWarningViewModel @ViewModelInject constructor(
   ...
) : ViewModel() {

This is what I am actually doing:

@AndroidEntryPoint
class RootWarningActivity : AppCompatActivity() {

    private val viewModel: RootWarningViewModel by viewModels()

}

And here is the complete crash log:
