I am getting the “Notebook not responding” error whenever I open ANY notebook. I closed my browser, reopened, navigated back to Observable in a single tab, and am still running into the problem on any of my notebooks. It even happens when I open up a new one. Any idea what is going on / what I can try to fix it?
All of a user’s notebooks share the the same process. If one notebook hangs, it will affect all other open notebooks from that user.
When the warning message appears, click “Safe mode”. That should switch all open notebooks into a text-only version.
If that doesn’t work, try the steps that are described in this comment:
