Error report by using Noto Serif SC font

Hello!

I'm sorry you're running into an error message when publishing your course! I'd like to start by understanding if this is an issue with the font or something else in the project? Have you tried creating a new project with text in the Noto Serif SC font to see if it publishes as expected? If it does publish as expected, then it might be another element in your course causing the error message.

If you're comfortable sharing your .story file, that will give us a good place to start. You can either attach it to this discussion or upload it privately in a support case.
