There is an issue packaging the project Unreal Stick Figure 2D project that is available in the learning tab. The project cannot package from the outset because of a couple of files that uses space as well as a few parenthesis in the file name. This causes the package to fail.
This issue occurs for the 4.14.3 and the 4.15.1 version of the project for download
