Goals

I am trying to update my apps and after I release to test flight it is crashing. Debugging the crash log and this is what I have found

Also find screenshot for reference

Video issue

https://github.com/facebook/facebook-ios-sdk/assets/34439120/1b0b5178-a932-470b-b105-6a143bd7805e

Expected results

It should not crash when initialising Facebook SDK. If I remove below line from AppDelegate.m, it works fine.

[[FBSDKApplicationDelegate sharedInstance] application:application didFinishLaunchingWithOptions:launchOptions];

But then, I have to remove Facebook login from my app.

Actual results

Currently app is crashing with below crash log, this crash is happening at initial launch as shown in video.

Steps to reproduce

We have an existing Facebook developer id that is causing this issue. We are not sure if this will happen for new developers who are going to integrate Facebook in their app. We are using Objective-c file for App Delegate.
