The app crashes when users download from AppStore and try to open the app, it shows launch screen and then crashes.
This happens only with real devices running iOS12.* App was built with Xcode 13.2.1.
Simulators and real devices running iOS13 and above are fine.
This is what the crash log obtained:
#0 (null) in __abort_with_payload ()
#5 (null) in _dyld_start ()
