Thread:VisualEditor/Feedback/VE freeze in Chrome when switching to code editor (2)

After editing https://fr.wikipedia.org/wiki/Adaptation_humaine_%C3%A0_la_haute_altitude for a while, I needed to switch to code, said that I would keep my changes and nothing happened except the page became grayed and froze. Clicked the green Save button but nothing. I can see my text but cannot select/copy it. Is it lost ???

in case it helps, here is what I see in the Chrome Console
