Navigation, Clear back stack when app stops

Question

I am using jetpack compose inside fragments flow, here the nav host

compose_view.apply {
    setViewCompositionStrategy(ViewCompositionStrategy.DisposeOnViewTreeLifecycleDestroyed)
    setContent {
        EggNavigation()
    }
}

    fun EggNavigation() {
        val navController = rememberNavController()
    
             NavHost(
            navController = navController,
            startDestination = EggScreenExotic.MainScreen.route
        ) {}
}

the navigation is something like this activity > fragment > compose egg list > egg details > open anther app >go to egg app > press back > activity is showing but activity >

but ...fragment > compose egg list > egg details > pressing back > egg list

why compose navigation is stop working
