Storyline 360 - When clicking preview, presentation closes

Hi Ronald!

Thank you for taking the time to reach out, and I'd love to help! To help us find the best way forward, could you confirm if this happens to your other Storyline projects? If you can preview other projects, it would be helpful to see the PowerPoint presentation so we can conduct some tests. 

Do you mind attaching your PowerPoint file to this discussion? You can also share it privately in a support case; we'll delete it when we're done!
