Storyline 360 new malfunctions

Wow. That sounds frustrating. Can you confirm that you are working locally on your C drive?  Since you are in a bind and under a  deadline, I recommend submitting a case to support 

As Ron suggested, you might want to submit a case to support.

Here’s some standard advice that the staff usually offers:

Be sure you only work on Storyline files located on your local hard drive.

Quit Storyline and relaunch it.

If that doesn’t help, try to repair Storyline:

Another option: Revert to an earlier version of Storyline. You can access other versions via the Articulate 360 app.

Both RonPrice​ and JudyNollet​ have great answers and check points. I have seen some issues with the latest update. I have had to go back a version or 2 in the past when i know it worked before the updates. 

Hi JohnDiFrancesca,

Sorry to hear that you're experiencing these issues with Storyline!

RonPrice and JudyNollet had great suggestions, and I see you've already connected with my teammate, Gian, in a case. We'll continue the troubleshooting there!

I have seen home tab go missing today. going to story view and back fixes it
