Error When Cooking for Windows

[kryC1]

I was able to build and run the project successfully in the Unreal Editor (UE 5.4 and Visual studio 2022), but when I attempt to cook the project (Development Configuration, Windows), the process fails with the following critical error:

UATHelper: Cooking (Windows): LogWindows: Error: appError called: Assertion failed: Enum [File:D:\build++UE5\Sync\Engine\Source\Runtime\CoreUObject\Private\UObject\EnumProperty.cpp] [Line: 315]

This occurs at the following code in FEnumProperty::ImportText_Internal:

EnumProperty.cpp
314. ...
315. check(Enum);
316. check(UnderlyingProp);
317. ...

Steps to Reproduce:

1. Clone this repository and build the project as per the instructions in the README.
2. Open the project in Unreal Engine 5.4.
3. Confirm it runs in the Editor without issues.
4. Attempt to cook the content for Windows in Development configuration.
5. Observe the crash.

Any workaround or fix would be appreciated.
Let me know if I can provide any test logs or help narrow it down.

Thanks!

Sorry for the delayed response.

I wasn't able to reproduce the error following the steps you provided on any of the computers I tested it on.

If you're still having issues with this, could you double check that the DIS Plugin submodule is in its most up to date state on your end by running the git submodule update --remote --merge command? Once this command runs you'll also want to rebuild the Unreal Project from source and then try cooking the project again.

Let me know if this fixes it for you or if you already found a fix for it.
