UE4 packaged game crashes on launch.

Consider this:

Exception Type:        EXC_BAD_ACCESS (SIGSEGV)
Exception Codes:       KERN_INVALID_ADDRESS at 0x0000000000000000

Your app crashed because it dereferenced nullptr. Look at the crashing thread’s backtrace:

Frame 28 shows that this code is running because of a dynamic linker initialiser. I think that frame 27 is a C++ static constructor. After that there’s a whole bunch of code that, from the perspective of this Apple crash report, looks like your code. I presume that you didn’t actually write this code, but rather it’s coming from your third-party library. If that’s the case, I recommend that you consult the support resources for that library.
