Launcher crashes during startup ("Process crashed with exit code 6")

What I expected to happen was...:
It was supposed to open the game as normal.

What actually happened was...:
I pressed "Play". My computer asks me if I want to reopen Java, as last time it crashed. I press "Reopen".

Steps to Reproduce:
1. Press the giant green "Play" button on the launcher.
2. Wait for a few seconds as it loads up.
3. Game crashes, with both my computer and the launcher alerting me to the problem.
