How to see my code after hitting hide code on th view tab (LIVE EDITOR)

As the title says I've pushed the hide code button and i'm not able to see the code back to normal, i've pushed it back and tried everything please help!

Same problem for me!

I have just upgraded to 2019a and found this problem!

This appears to be a bug. If we start Matlab R2019a new after hiding the code a message appears, that tells to contact technical support. Tried with R2019a Update 1.

I had the same problem today using R2022b (Update 3), so the problem is still not fixed, it seems.

I just wanted to see how the document would look with hidden code, but then I was stuck!

Luckily, I could restore an old version from my Dropbox account. The workaround in the bugreport would also have done the job, I guess. I would prefer a less circumspect solution, though. Or a warning when you click the hide button, like: "This action is irreversible. Are you sure you will never want look at the code parts?"

Have you checked the bugreports page? Seems like a known issue:

Just ran into this bug or someting like it that triggered all code being hidden. A Select all (control A) returned my script to showing the code and working today.
