Hi Christina!
I'm sorry to hear that text-to-speech audio is causing Storyline to crash!
Testing the behavior on my end (Storyline 360 ver. 3.80.31058.0 via Windows Parallels on a Mac M1) I was able to add TTS audio without issue. Everything was working as expected!
It's possible new elements added to the course may have caused some form of file corruption. Not to worry! I'd be happy to take a closer look at your .story file if you're comfortable sharing! Feel free to attach it here in the discussion or privately through a support case.
Also, if you're encountering any error message when Storyline crashes it would be helpful to see a screenshot of what the message says.
Looking forward to hearing from you!
