UE 5.4 Game Instantly Crash on iOS devices on Testflight

Hi,

I'm working on a game for the past few years using first Unreal Engine 4, and now Unreal Engine 5.4.4. I'm experiencingan unusual crash on startup on some devices . The crash is so fast that I'm barely able to see the launching screen sometimes because the app closes itself before that.

I got a EXC_CRASH (SIGABRT) so I know that it's a null pointer reference, but I can't quite wrap my head about the cause, I think that's something messed up in the packaging of the app, but here is where I'm blocked, I'm not that accustomed with apple devices.

If someone has some advise to give, please, any help will be very valuable. Many thanks.
