UE4 4.10.1 PackagingResults:Error: Error Unknown Cook Failure

I have tried reimporting every blueprint and asset individually into a new project and still get this error, I know it’s a problem with one/multiple of my blueprints as I tried importing everything except them and had no problems exporting.

I have moved things around in Windows Explorer but trying the official migrate option has helped nothing either. I am completely at a loss; everything works beautifully in editor and even when I launch from editor. On export, however, I fail.

This is a Blueprint-only project.

Attached is my OutputLog. Would anyone be able to help?

Output Log

EDIT: This is the “handled error” which is what I think causes the build failure.

Hey SimpleAsThat,

Here are the errors I found within your project. Please focus on the errors first, and then the warnings. Typically the errors are what causes your packaging process to fail.

It looks like you’re having an issue with the Event Graph.

MainFrameActions: Packaging (Windows (64-bit)): UE4Editor-Cmd: Ensure condition failed: Context.IsEventGraph() || !Context.EventGraphLocals.Num() [File:D:\BuildFarm\buildmachine_++depot+UE4-Releases+4.10\Engine\Source\Editor\KismetCompiler\Private\KismetCompiler.cpp] [Line: 756]

This looks like you’re having a .dll issue due to an output device. Do you have any devices attached to your computer, such as a tablet?

Let me know what you find out, please send updated logs.

SimpleAsThat,
