I developed an Unreal Engine game made in C++ and for some reason, it doesn’t want to package. It kept saying Unknown Error and the txt file is a bit confusing as well. I tried finding a solution but still haven’t found a proper one. Its a bit confusing because I can’t find an obvious error in it. Here is the logs from the txt file :

Investigating your issue through the community, a very similar situation was encountered in three other threads. Please test their solutions for your scenario, hope it helps:

Thanks for that, it was very useful! I fixed it by modifying the Build file by including the “UMG” in the PublicDependencyModuleNames and I moved the “UMGEditor” module into the editor-only dependencies!

EDIT : [https://youtu.be/HhW4O2XhdZQ?si=ymeChvonPjp-XXU4](https://youtu.be/HhW4O2XhdZQ?si=ymeChvonPjp-XXU4)  
I did what the video said as well

```
// Add core dependencies		
PublicDependencyModuleNames.AddRange(new string[] 
{ "Core", 
"CoreUObject", 
"Engine", 
"InputCore", 
"EnhancedInput", 
"FMODStudio", "UMG" });

	// Conditionally add editor-only dependencies
	if (Target.bBuildEditor)
	{
		PrivateDependencyModuleNames.AddRange(new string[] 
		{ 
			"UnrealEd", 
			"UMGEditor", 
			"SequencerCore", 
			"CurveEditor", 
			"PropertyEditor", 
			"EditorConfig" 
		});
	}

```
