App crash when open from Kill state through Push notification Objective C iOS

Question

My app working fine when app is in background and open it by clicking on Push Notification. But if I terminate app and open it through push notification then app crash. I also integrate Crashlytics. Here is attached photo & code. App crash only in one type of notification.It is not data parsing issue.

    - (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
    UNUserNotificationCenter *center = [UNUserNotificationCenter currentNotificationCenter];
    [center requestAuthorizationWithOptions:(UNAuthorizationOptionBadge | UNAuthorizationOptionSound | UNAuthorizationOptionAlert)
                          completionHandler:^(BOOL granted, NSError * _Nullable error) {
                              if (!error) {
                                  NSLog(@"request authorization succeeded!");
                                  //[self showAlert];
                              }
                          }];




// Branch Intigration
    Branch *branch = [Branch getInstance];

//    if is debug
//    [[Branch getInstance] setDebug];


    [branch initSessionWithLaunchOptions:launchOptions andRegisterDeepLinkHandler:^(NSDictionary *params, NSError *error) {
        if (!error && params) {
            DecisionController * mainVC = [[DecisionController alloc] init];
            [mainVC viewDidLoad];
            // params are the deep linked params associated with the link that the user clicked -> was re-directed to this app
            // params will be empty if no data found
            // ... insert custom logic here ...
            NSString * non_branch_link  = [params objectForKey:@"+clicked_branch_link"];
            if ([[params objectForKey:@"+clicked_branch_link"] boolValue]) {
                NSNotificationCenter* nc = [NSNotificationCenter defaultCenter];
                [nc postNotificationName:@"DeepLinkNotification" object:self userInfo:params];
            }
            NSLog(@"params: %@", params.description);
        }
    }];

    // MAGICAL RECORD Intigration

//    [Fabric with:@[[branch class]]];
    NSLog(@"magical record path to SQLite base %@", [NSPersistentStore MR_defaultLocalStoreUrl]);

The issue is that you get the notification that opens the app from launchOptions of didFinishLaunchingWithOptions method and deliver to the same function that handles it when app is opened and perform a push / present that makes the app crash as windows's root view controller is not yet set , so delay that until app it being active
