Android - Crash "FragmentManagerImpl.checkStateLoss"

Question

I am working on an Android project → Target SDK Version - 25 Build Tools Version 25.0.2

Currently, I started getting StateLoss Crash. Search on Google, found many answers on Stackoverflow.

First of all, I can not imitate this problem. Just view this issue in Crashlytics as

Fatal Exception: java.lang.IllegalStateException
Can not perform this action after onSaveInstanceState

There is not enough information in the stack trace to understand. After some searching, I think the problem is with committing fragments. My example commit code is shown below. Please note that all commits are made internally.onPostResume()

Fragment f = getSupportFragmentManager().findFragmentByTag("LandingFragment");
android.support.v4.app.FragmentTransaction tr = getSupportFragmentManager().beginTransaction();

        if(f == null && !isFinishing() && !isDestroyed()){

            f = new LandingFragment();
            tr.replace(R.id.onboarding_view_fragment_container, f, "LandingFragment");
            tr.commit();
        }
