UBT: Failed to Produce Item. Game.exe

So, whilst following Epic’s Wiki of “properly” packaging and releasing: Releasing Your Project | Unreal Engine Documentation

And it runs properly until it gets to a certain stage, the Build stage. Then it displays a number of errors, which in the Project Launcher Log Do Not appear Red, but just the simple white text.

Then it gives me this line: UnrealBuildTool: ERROR: UBT ERROR: Failed to produce item: %Location%\Documents\Unreal Projects\LurkingInTheShadows\Binaries\Win64\LurkingInTheShadows.exe

I’m pretty sure it’s Rama’s Victory BP Library since that are where the errors are coming from, but I’ll have to investigate!

Linking errors. Hard to tell what’s going wrong. There’re warnings of your Build.cs files. It seems you’ve updated your project from old engine versions. Try to eliminate these warnings and clean up your project then have a fresh rebuild.

Solved by cleaning up and tidying the project. Props to J0000J
