You mentioned exports, so I wasn’t sure if you could package a completely new project.
You definitely should back up just to be on the safe side, but I don’t think anything wacky will happen. I’ve been mainly recommending this for Android packaging and people seeing the ant.bat error (which also masquerades as UnrealBuildTool failure), so I’m suspicious that it’s something related, so I’m actually really curious to see if this works. Definitely just the intermediate for your project, not for the editor.
Further, I’m seeing this in your project: Ensure condition failed: (TextureWidth > 0) && (TextureHeight > 0) [File:D:\BuildFarm\buildmachine_++depot+UE4-Releases+4.7\Engine\Plugins\2D\Paper2D\Source\Paper2D\Private\PaperSprite.cpp] [Line: 817]
I’m not by any means an expert with ensures, but I believe this means it’s looking for something related to your use of Paper2D and can’t find. So that’s something for you to check out on your end, if you can.
