I don't understand from crash logs

Hi,
I just released new version of my application but I get an error that is only seen on iphone 11 pro phones. I examine crash log from Xcode but I could not understand why the error was caused, the error log is as follows, how can I understand where the real error originated?

Here is the original crash log:

Exception Type: EXC_CRASH (SIGABRT)

From the stack trace, there is call to UIKitCore
endGeneratingDeviceOrientationNotifications method and either parameters of that call or something with application or UI state isn’t right for that call to go trough

Googling on “ios endGeneratingDeviceOrientationNotifications crash” gives number of results, including this:
