Packaged Project Crashes when Opened, No Errors during packaging (UE5-02)

Development Programming & Scripting
1

Using Unreal Engine 5.0.2

I fully packaged my project in UE5, and in the output log there’s not a single warning nor error. No issues.

However, whenever I open the packaged project, I just get “Fatal Error” and it instantly crashes. The log (atleast what I assume is the log) “Manifest_UFSFiles_Win64” is not telling me anything has errors or anything critical that could be causing this issue. Would love some help on this one because been racking my brain on this for days.

Just want to restate that in the Output Log of the editor, when I packaged the project, it says “UATHelper: Packaging (Windows): LogInit: Display: Success - 0 error(s), 0 warning(s)”. So no warnings or errors are found, and my “Game Default Map” is setup correctly, and everything works properly in editor.

did you specifically added the maps in the package settings area?

That option is buried under a small arrow.

you need to add each map you use in the game in that section.

I don’t think unreal will pack the referenced maps automatically. From what I’m seeing if you don’t pack the maps your game will not work.

I looked at this help section and I can’t seem to find that option mentioned.

that is not nice.

the option I think is

List of maps to include in a packaged build

or something. is an array just add all maps there one by one including the main one. don’t forget about that

yea i added them correctly. If i didn’t, it would’ve caused some error messages due to reference to said maps.

I faced the same issue today within the 5.0.3 version.

In my case, the reason for that was a reference to the empty level in the logic. In general, the main level blueprint logic referred to the level that was used for the level streaming. I cleaned the level earlier but didn’t remove the reference from the main level blueprint.

Once I removed the useless node, the packaged app stop crashing.
