Component used: Navigation

Version used: 2.4.0-beta02

Devices/Android versions reproduced on: Every device

I'm using Compose with the navigation components. I inject a ViewModel via Hilt.

I navigate with the NavGraphBuilder.composable() extension, which works.

When I open my composable within a Dialog via the NavGraphBuilder.dialog() extension I run into the following problem:

Closing the dialog with the system back button works. When I call navController.popBackstack() this exception occurs and the app crashes:

java.lang.IllegalStateException: You cannot access the NavBackStackEntry's ViewModels until it is added to the NavController's back stack (i.e., the Lifecycle of the NavBackStackEntry reaches the CREATED state).
        at androidx.navigation.NavBackStackEntry.getViewModelStore(NavBackStackEntry.kt:180)
        at androidx.lifecycle.ViewModelProvider.<init>(ViewModelProvider.java:114)
        at androidx.lifecycle.viewmodel.compose.ViewModelKt.get(ViewModel.kt:80)
        at androidx.lifecycle.viewmodel.compose.ViewModelKt.viewModel(ViewModel.kt:72)

I observed that my crashing composable is recomposed after navController.popBackstack(), which ultimately leads to the crash. Is there a reason for the additional recompositions?
