Hi Jay,
Sorry to hear that you ran into this behavior.
I'd like to ask a few questions to help clarify your experience.
- Are you working locally when making edits to your project file? Or are you working directly on a network drive?
- Do you have an application that syncs your folder directly to a network location such as OneDrive?
If you're working locally, I'd recommend doing a repair of your Storyline 360 installation to see if this helps address the frequent crashes. Additionally, I'd like to share this article which lists some scenarios which might cause you to lose your project file, as well as how to prevent them.
If the issue persists, open a case with our support team here so we can take a closer look at why you're experiencing such frequent crashes.
