The scenario is when the app is on Fragment A and then kept the app in the background for some time. After resuming from the background the initial state of the app is in Fragment A but then suddenly app restarts from startDestination in the navigation component causing the below crash.
Fatal Exception: java.lang.IllegalArgumentException: Navigation action/destination com.app.gulfcraftv2:id/action_splashFragment_to_nav_home cannot be found from the current destination Destination(com.app.gulfcraftv2:id/companyFragment) class=com.precise.gulfcraft.ui.companydetail.CompanyDetailFragment

The crash is happening in the below section.
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
try {
Handler(Looper.getMainLooper()).postDelayed({
findNavController().navigate(SplashFragmentDirections.actionSplashFragmentToNavHome())
}, 3000)
} catch (e: Exception) {
}
}
check first if this is your current destination with following function
fun navigate(destination: NavDirections) = with(findNavController()) {
currentDestination?.getAction(destination.actionId)
?.let { navigate(destination) }
}
