Component used: Navigation Version used: Navigation Compose 2.8.2

Devices/Android versions reproduced on: Pixel 9 Pro, Simulator

Imagine this Navigation structure:

NavHost {
  composable<A>
  navigation<B> {
    composable<C>{}
  }
}

In composable C I am loading a viewModel() with the backstackEntry of B as viewModelStoreOwner. Now I am navigation from A to B, and from B again to B. When navigation back using popBackStack() everything works as expected. When navigation back using the Back Gesture with Predictive Back enabled in the Manifest the app crashes when going from A-B-B to A-B.

java.lang.IllegalStateException: You cannot access the NavBackStackEntry's ViewModels after the NavBackStackEntry is destroyed.
