File not getting save as getting object reference error.

Hi Learning Desk, and thanks for reaching out!

I'm sorry to hear you're experiencing this issue and I'm happy to help troubleshoot. I have a few clarifying questions to start.

1. Are you working from your local drive or network drive? We recommend you save and publish Storyline projects on your local hard drive (typically your C: drive). Working on a network drive or an external USB drive can cause erratic behavior.
2. Is this happening with one file or multiple files? If just this one, have you tried importing your slides into a new Storyline project?
3. Are you able to preview this project? If so, are you seeing an error message or unexpected behavior?

If the issue persists, I'd like to connect you with one of our talented Support Engineers to investigate further. You can reach them here!
