I hope can help me with this specific bug: Apps crashes when is download from TestFlight without more information in log crash. This is the context:
- I tested the app in two iPhones (iOS 12.x and 14.x) from Xcode (running debug environment) and both work fine
- I tested the app in two iPhones (iOS 12.x and 14.x) from Xcode (running release environment) and both work perfectly
- I tested the app in two iPhones (iOS 12.x and 14.x) from TestFlight (release environment obviously) and iOS 12.x work perfectly but iOS 14.x crash when change view, I suppose trying to make a push
I extracted the log file from this crash and the information is not clear, for example Exception Type shows EXC_CRASH (SIGABRT) and Exception Note says EXC_CORPSE_NOTIFY with Application Specific Information: abort() called, but Last Exception Backtrace show data like memory access references without clear information. I paste the log for more information:

I tested my app with Xcode 12.1 and then with Xcode 12.2 with BigSur but I think it doesn't matter, because the real problem is between TestFlight and iOS 14.x. Also, the app is developed in Objective-C yet without Swift. Anyone has another way to get the error or know what is happening?
Aditional:
I attach symbolic crash
