Application runs into ANR before having App onCreate() called

I’ve been working on a project for a very long time.
Recently I started to have a ANR problem right on application startup.
In fact, since the App.onCreate() method is never called the application is not even starting. As far as I know the only thing that is called before that is the onCreate() method of any ContentProvider. So i removed them from the manifest file but the problem stays the same. App.onCreate still not called.

Here are some additional details:

FCMIDService class:

public class FCMIDService extends FirebaseInstanceIdService{

    private static final String TAG = "FCMIDService";

    /**
     * Called if InstanceID token is updated. This may occur if the security of
     * the previous token had been compromised. Note that this is called when the InstanceID token
     * is initially generated so this is where you would retrieve the token.
     */
    @Override
    public void onTokenRefresh() {
        CLog.d(TAG, "FCM id received");
        // Get updated InstanceID token.
        String token = FirebaseInstanceId.getInstance().getToken();
        //Do something with the token
        //...
    }

    @Override
    public void onCreate() {
        Log.d("atf", "on create here called");
        super.onCreate();
    }
}

According to Logs the ANR falls into FCMIDService class but that doesn’t make sense. When I debug the application the onCreate() method is never called. So how can the ANR fall in there if it never gets executed?

Another important notice:
When I rolled back the code to a previous working version (via SVN) the same issue persisted which makes me think that the repository of one of the libraries I use got changed.

EDIT2:
After a little bit of experimenting I found out that the problem is caused by Facebook integration.
When I removed the line

"implementation 'com.facebook.android:facebook-android-sdk:[4,5)'" 

and all of Java code related to it, the ANR disappeared.
I can’t resign on Facebook implementation so I replaced

"implementation 'com.facebook.android:facebook-android-sdk:[4,5)'" 

with

"api 'com.facebook.android:facebook-android-sdk:4.36.0'" 

acording to https://mvnrepository.com/artifact/com.facebook.android/facebook-android-sdk/3.19.0 . But that didn’t work.

Any ideas of a work around?
