Unreal Engine Fatal crash while packed for shipping 0x0000000000000008

smallgamedevfun · January 20, 2025, 2:30pm

While working in Editor even using Launch game from .uproject, it works fine, but after using Project Launcher to pack the game in shipping form the game crashes with Fatal Error!. From crash error it seems to be an error because localization, and I also tried to read from .dmp but I can’t understand what causes it from this one.

I only have localization for 2 languages and both are selected from culture list in Project Launcher.

This is the error:

Fatal error!

I made a copy of the game and removed all Game Targets, but after packing the game, still the same error.

smallgamedevfun · January 23, 2025, 9:15am

I narrowed down the problem to Project Launcher, because if I use the other way to pack the game it works and all languages are available, meaning from Level / Platforms / Windows / Package Project with Binary configuration set to “Use project settings (Shipping)”.

These are the settings inside Project Launcher:

Build: Detect Automatically
Build Configuration: Shipping
Build UAT checked
Cook: By the book
Cooked Platforms: Windows
Cooked Cultures: Same as in Project Settings / Packaging / Languages to Package
Cooked Maps: All maps are selected
Create a release version of the game for distribution checked
Name of the new release: Some name
Advanced Settings: “Iterative cooking” and “Don’t Include…” are checked the rest unchecked
Http unchecked
Cooker build configuration: Shipping
Package: Package & store locally
Is this build for distribution to public checked
Include an installer checked
User container unchecked
Make a binary config checked
Archive unchecked
Deploy: Do not deploy

Do I need to change something?

Do I need to change some settings here?

So it seems that the problem was with Make a binary config file for faster runtime startup times, but even if that is checked the config file wasn’t binary it was still normal “.ini” file.

If I uncheck that then I don’t get that crash at startup. Can someone tell me what that option is suppose to do and maybe why it was causing the crash?

Zen.Dev · August 5, 2025, 12:09am

Thanks for pointing out a solution, worked like a charm for me!
Still, I do not actually know, why this issue happens. I guess, it’s just some bug in this exact version of engine (5.5.x), because I haven’t found any mentions of this error on versions before that, and that happened with me on version 5.5.4
Idk if it was fixed already in 5.6, but if not, someone should probably test it out and file a bugreport to Epic.
