PackagingResults:Error: Error Unknown Error

Hello all!

I am trying to launch on windows, and I am using perforce as source control. The output log can be seen here: Output Error - Pastebin.com

So far this game is a simple copy of the endless runner tutorial, with the addition of a main menu from a partner that uses a widget blueprint and a single texture as far as I know.

I kind of think this is a perforce created error, most build errors are from being unable to write and delete files.

From cook.txt (when trying other launch methods via project launcher):

Also error generated when trying to launch standalone preview (or standalone from the ‘play’ button menu next to launch if that is the incorrect title)
Unable to save package to
