To reproduce, start with one buffer with unsaved content.

1. Turn on status-stats.
2. Close the dirty buffer. You'll see the "do you want to save?" dialog.
3. Do not save the file. Now you should see the notification of an uncaught TypeError.

After dismissing the caught TypeError dialog, I can successfully close the dirty buffer. (I have to choose again not save it to a file.) After this, if I try to create a new buffer, I see no editor pane and therefore can't see any of the text I type. I can open several new buffers and I see no editor pane. See screenshot:

After I close the window (and not just all the tabs without editor panes), I can create a new buffer that behaves as expected: the editor pane appears and I can type into it.

From here, I can reproduce the entire chain of events.

This also happens if the current active pane is not a text editor, but instead (for example) a Markdown preview window.
