Help with publishing error

Hi, I'm creating a course that is a consolidation of several modules. Each module has it's own quiz and results slide, and then I have a final Results slide that pulls the results from the other Results slides. In order to pass, the user must score 80% or higher on each result. I have created five or six other similar courses with no issue.

The course seems to work ok in Preview, however when I try publishing either to LMS or to Review 360 I get the following error at the point in the publishing process where it is writing the Launch sequence:

I am attaching the source file as well. Any help would be appreciated.
