Android App in kotlin keeps crashing

Android App built with Kotlin keeps crashing. I have a search bar with a Menu Item(Search Icon) in my App. when the user clicks on the Search Icon in the Action bar. A new Activity is opened which has an EditText that gets focused automatically. But when the user clicks the back button in Action bar just after opening the activity. the app gets crashed after finishing Search Activity. this is the function that is executed when the user clicks the back button.

Note The back button here is not from the navigation buttons instead it is from the toolbar (Action bar). Also This crash occurs only in API Level 22 Lollipop, API LEVEL 23 Marshmallow. The App works perfectly in Jellybean, KitKat, Oreo.

override fun onOptionsItemSelected(item: MenuItem?): Boolean {
        if (item!!.itemId == android.R.id.home) {
            finish()
        }
        return super.onOptionsItemSelected(item)
    }

Here is the exception that is being displayed in Android Studio.

try deleting .gradle folder in your project directory and then rebuild your project after clearing build cache.

You have a NullPointerException. You are using Kotlin so you are not supposed to get this. Unless you are not using Kotlin null safety properly. Read thiis Kotlin Null Safety
