Notice in your log it says “UnrealBuildTool: LINK : fatal error LNK1181: cannot open input file ‘C:\Program Files (x86)\Epic Games\4.14\Engine\Plugins\Marketplace\AllrightRig\Binaries\Win64\UE4-ARigRuntime.lib’”
It appears you have a plugin that is either incompatible with the version of your engine, or it is just causing problems when trying to package. I would take a look at this plugin for starters.
Let me know if you have further questions.
Thank you,
