It was working fine before and all of a sudden I the toolbar relevant to VSCode wasn't showing up at the top of my screen so I decided to close VSCode but now this is happening. I've been getting it every time I try to open VSCode

Uncaught Exception:

I tried uninstalling and reinstalling but to no avail. I'm running Ubunutu 16.04 LTS. Any tips?

Edit: After a minute or two, a window pops up that says I have another instance of VSCode running and should close all of them before starting it again. How would I go about doing this? Tried doing killall code but that didn't seem to work as code is probably not the right thing to say.
