System wide hex error: `failed to start child: Hex.State`

I was tinkering with my current project, when I accidentally stopped my iex session. When I tried to restart I was greeted with the following error:

$ mix hex

14:16:25.094 [notice] Application hex exited: Hex.Application.start(:normal, []) returned an error: shutdown: failed to start child: Hex.State
    ** (EXIT) an exception was raised:

What happend? This happens system wide when trying any hex command. I even tried re-installing both hex and Elixir itself, but to no avail.
