This started happening within the last one hour. Before that, I was able to complete a full regression cycle on VE, then I noticed an option "Mention a user" under Insert menu. Clicking on which was doing nothing but there was an error in the console. Then it disappeared the next minute and after that I am not being able to open VE at all.
