Black screen


Editing a list-item on my Mac results a black screen after I hit ENTER. It seems that only happening when I have a text and a number separated with a space in the list-item and straight followed by a span. Then when I doubleclick in the list-item text, just on the number, the app throws a black screen. My code is like below, and when I click on 1 (in the visual panel not on the HTML panel) the app goes black.

<li>Item 1<span>Text</span></li>

Can you try reinstalling/resetting the app? You can learn how this is done here:

I tried that, still happening. I am on macOS Catalina v10.15.4
