abort_with_payload : app crash after launch on iOS12.5 (real device only)

Has anyone experienced an app crash with iOS12.* or below?

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.*

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 ()

I checked the solutions from StackOverflow such as:

• disabling "Enable guard Malloc" (was always disabled)
• clean (always clean before archive)

And other solutions I didn't try yet, but I can't test on a real device if it works since I don't have an iPhone with iOS12.

• Change developer certificate in Keychain to "always trust"
• Pod update

Any suggestions are highly appreciated! Thank you in advance.
