Component used: Navigation Version used: 2.9.0-alpha05 Devices/Android versions reproduced on: 33

I have two nested navHostController mainNavController dashboardNavController

in dashboardNavHost when i switch between tabs with this code :

dashboardNavController.navigate(rout) { popUpTo(dashboardNavController.graph.startDestinationId) { saveState = true } launchSingleTop = true restoreState = true }

and then with mainNavController go to other composable screen, when popup back, i get the following error:

java.lang.IllegalStateException: The saved state value associated with the key 'android-support-nav:controller:backStackIds' is either null or not of the expected type. This might happen if the value was saved with a different type or if the saved state has been modified unexpectedly. at androidx.navigation.NavController.restoreState(NavController.android.kt:3697) at androidx.navigation.compose.NavHostControllerKt$NavControllerSaver$2.invoke(NavHostController.kt:80) at androidx.navigation.compose.NavHostControllerKt$NavControllerSaver$2.invoke(NavHostController.kt:78) at androidx.compose.runtime.saveable.SaverKt$Saver$1.restore(Saver.kt:65) at androidx.compose.runtime.saveable.RememberSaveableKt.rememberSaveable(RememberSaveable.kt:86) at androidx.navigation.compose.NavHostControllerKt.rememberNavController(NavHostController.kt:59)
