Error Report when publishing to an LMS

Hello,

I have been receiving this error message with some, but not all, of my Storyline 360 files when attempting to publish to LMS. I know there is nothing wrong with the file as I can send it to a colleague and they are able to publish it. I have run all updates, and even uninstalled and reinstalled Storyline.

Can you please advise on why this is happening, and how I can fix it? It is an inconvenience on my colleagues that I have to keep sending them files so they can publish them for me. All other aspects of Storyline 360 are working- I can open, edit and save files with no issue.

Kind regards,

Leigh
