App launch time too slow when launched from call kit answer call button

i have an app with video call integrated and call kit integrated totally fine. when i cold launch the app launch time is absolutely normal.

Now if my app is terminated and i recieve voip notification and see call kit banner and i accept the call from there, it launches my app. But it freezes like for 5 to 10 secs on a white screen. it happens everytime when i receive call and pick it up while app is in terminated state. i also loose the audio in these scenario.

Need help to figure out if app launching from call kit answer call action and from normal tap on icon is any different?
