I figured out what the problem is: In your presentation, Lyx uses bitmapped fonts for the presentation, and IpePresenter does not support those.
You can easily check this if you open the presentation with a PDF viewer and look at the list of fonts in the document properties: It will show several embedded "Type 3" fonts with name "No name".
Type 3 fonts are bitmapped fonts. In 2019, no text-processing system should use those without warning the user, so I think something is wrong either with Lyx or with the template you are using.
I managed to get the presentation to work by going (in Lyx) to Document -> Settings -> Fonts, and changing "Roman" to "Times Roman" and "Sans Serif" to "Helvetica".
I will add something to IpePresenter so that it will show an error message explaining what the problem is.
