We have an app which works on device when built via XCode 12.5.1.
But, when we build same app via XCode 13.2.1, it crashes on launch. No crash logs as app does not finish launching.
Symbolicated native crash device log from XCode:
1 libsystem_pthread.dylib 0x00000001ddaaf9e8 pthread_kill + 212
2 libsystem_c.dylib 0x00000001a0ea79b0 __abort + 112
3 libsystem_c.dylib 0x00000001a0ea7940 __abort + 0

9 iOS 0x0000000102bfd07c llvm_throw_corlib_exception_abs_trampoline + 172
10 iOS 0x00000001037d601c
No issues on Simulator. Able to deploy on Debug mode on device as well.
I will really appreciate, if any one can hint to the cause. Thanks!
