Error Code

Took 2444.5545271s to run UnrealBuildTool.exe, ExitCode=6 UATHelper: Packaging (Windows (64-bit)): UnrealBuildTool failed. See log for more details. (C:\Tools\UnrealEngine\Engine\Programs\AutomationTool\Saved\Logs\UBT-UE426-Win64-Development.txt) UATHelper: Packaging (Windows (64-bit)): AutomationTool exiting with ExitCode=6 (6) UATHelper: Packaging (Windows (64-bit)): BUILD FAILED PackagingResults: Error: Unknown Error

Context I ran Unreal Engine 4 from the source code in Visual Studio. After adding assets, I realized that I ran out of space, so I uninstalled Visual Studio since I didn’t know that I would need this to actually package the whole thing. I reinstalled it then, built the UE4.sln file, and built the AutomationTool as well. However, after packaging all 700+ files, it gave me the error code I specified in the first section of this post.
