Trouble finding reason for Build Fail for Win 64 v4.8.3

Hello! I hope someone can help me out. I have recently tried to build my project (which is using UE v4.8.3) and started getting build errors. I think I located the problem in the Log files, but am not sure what to do to fix it. Here is the log entries I think are the culprit…

MainFrameActions: Packaging (Windows (64-bit)): UE4Editor-Cmd: [2018.02.11-15.13.05:260][ 0]LogWindows: === Critical error: ===
MainFrameActions: Packaging (Windows (64-bit)): UE4Editor-Cmd:
MainFrameActions: Packaging (Windows (64-bit)): UE4Editor-Cmd: Fatal error: [File:D:\BuildFarm\buildmachine_++depot+UE4-Releases+4.8\Engine\Source\Runtime\Engine\Private\ShaderCompiler\ShaderCompiler.cpp] [Line: 615]
MainFrameActions: Packaging (Windows (64-bit)): UE4Editor-Cmd: Shader Compiling thread exception:

MainFrameActions: Packaging (Windows (64-bit)): UE4Editor-Cmd: Worker returned 10 jobs, 3 expected

As far as I can tell, all of the other errors in the log are minimal missing link errors that shouldn’t affect the build (since I was able to successfully build the project with them before). It seem like some kind of Shader process error?

Just in case I will attach the full log.

Any help resolving this would be greatly appreciated!

Found the error. I had a “conflicted copy” of one of the maps in the the folder that wasn’t being recognized. After deleting it…the build went thru successfully!
