Cannot Open Visual Studio Code

I've installed VS Code on my laptop with Ubuntu 16.04 LTS. I've tried multiple installation methods with identical results; most recently, I followed the "new" instructions from Cactux here. I've tried opening the application two ways to no effect.

• When I open the program from 'Applications', the icon shows in the launcher for approximately 15 seconds and then disappears. No error pops up.
• When I open a terminal and type code, the command does nothing and I get a new prompt in less than a second.

I'm struggling with what to try since I'm relatively new to Linux. which code yields /usr/bin/code, which is a bash script. This is where I get outside my depth.

        fi
    done
    if [ -z $CAN_LAUNCH_AS_ROOT ]; then
        echo "You are trying to start vscode as a super user which is not recommended. If you really want to, you must specify an alternate user data directory using the --user-data-dir argument." 1>&2
