App Review Denied, Can't Replicate, this is one of the crash logs provided

As the title says, my app update review was denied. The app is functioning completely normally on any test device/emulator I use. They are saying the app launches to a black screen and then crashes. Can anyone help me out here because I am completely stuck.

Do you do some external data launch or heavy computing before showing the first screen ? It seems it take 19 seconds which may be too long.

Your crash report has this:

Termination Reason: FRONTBOARD 23…05 $(termination.indicator)

23…05 is 0x8badf00d, as discussed in Addressing Watchdog Terminations. The backtrace of the main thread looks like this:

Thread 0 Crashed::   Dispatch queue: com.apple.main-thread
0   libsystem_kernel.dylib        	       0x1b807ced0 connect + 8
1   ProApp.iOS                    	       0x105d5ff48
…
44  ProApp.iOS                    	       0x104836280
45  UIKitCore                     	       0x18379d004 -[UIViewController 
    _sendViewDidLoadWithAppearanceProxyObjectTaggingEnabled] + 108 

Frame 0 indicates that you’re stuck in the BSD Sockets connect system call. It seems that your app is trying to do synchronous networking on the main thread, which never ends well.

Frames 1 through 44 are not symbolicated, which makes it hard to track this down further. Is a next step I recommend that you fix that, per the advice in Adding Identifiable Symbol Names to a Crash Report.
