Description
Component used: Navigation
Version used: androidx.navigation:navigation-compose:2.4.0-beta02
Devices/Android versions reproduced on: Google Pixel 3 with Android 12, ARM64 emulator with Android 12
Please get the attached project (Compose Blueprint). It contains two screens: Main and Subscreen. Subscreen is nested under Subgraph navigation block. So the navigation goes: Main -> Subgraph -> SubScreen. Subscreen is requesting Subgraph's ViewModel emulating the situation when this ViewModel needs to be shared between some screen within a nested flow.
Install the app and follow the next steps:
The same crash never happen when the activity is not recreated, e.g. when "Don't keep activities" is disabled. Also, just going back and forth between screens without moving the app into the background works correctly.
So it seems there something going wrong when the navigation backstack is restored.
