IOS app is not starting

I have a React-Native project. This project begun with Expo then it has been ejected switched to react-native. Last week i have updated an expo library that was available in it, i begins to get errors and i was not able to start the project anymore. What i have made, i have removed all expo libraries used, and i have succeeded to start it up on android... But on IOS, it's running without debug problems, but when i start the app it shows the splash screen then it fadeout without starting the first app screen. It seems like onSplashscreen.hide, its not opening the app first screen

I think that a person that woks on native language on xcode (swift or objective c) may directly diagnose the problem.

Can someone help me with

This is my appdelegate.m file

#import <React/RCTBridge.h>
#import <React/RCTBundleURLProvider.h>
#import <React/RCTRootView.h>
#import <React/RCTLinkingManager.h>

@interface AppDelegate () <RCTBridgeDelegate>
@property (nonatomic, strong) NSDictionary *launchOptions;
@end

@implementation AppDelegate

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{  
   self.launchOptions = launchOptions;
  self.window = [[UIWindow alloc] initWithFrame:[UIScreen mainScreen].bounds];
  
  [self initializeReactNativeApp];
  // [super application:application didFinishLaunchingWithOptions:launchOptions];

  return YES;
}

- (RCTBridge *)initializeReactNativeApp
{
  RCTBridge *bridge = [[RCTBridge alloc] initWithDelegate:self launchOptions:self.launchOptions];
  RCTRootView *rootView = [[RCTRootView alloc] initWithBridge:bridge moduleName:@"main" initialProperties:nil];
  rootView.backgroundColor = [[UIColor alloc] initWithRed:1.0f green:1.0f blue:1.0f alpha:1];

  UIViewController *rootViewController = [UIViewController new];
  rootViewController.view = rootView;
  self.window.rootViewController = rootViewController;
  [self.window makeKeyAndVisible];

  return bridge;
 }

- (NSURL *)sourceURLForBridge:(RCTBridge *)bridge {
 #ifdef DEBUG
  return [[RCTBundleURLProvider sharedSettings] jsBundleURLForBundleRoot:@"index" fallbackResource:nil];
 #else
  return [[NSBundle mainBundle] URLForResource:@"index" withExtension:@"jsbundle"];
 #endif
}

- (BOOL)application:(UIApplication *)application
   openURL:(NSURL *)url
   options:(NSDictionary<UIApplicationOpenURLOptionsKey,id> *)options
{
  return [RCTLinkingManager application:application openURL:url options:options];
