Crashes if mix dependencies dont have .formatter.exs file

[LukasKnuth]

Environment

• Elixir & Erlang versions (elixir --version): Erlang/OTP 22 / Elixir 1.11.1
• Operating system: Mac OS X 10.15.7
• Editor or IDE name (e.g. Emacs/VSCode): VSCode
• Editor Plugin/LSP Client name: jakebecker.elixir-ls

Troubleshooting

• Restart your editor (which will restart ElixirLS) sometimes fixes issues
• Stop your editor, remove the entire .elixir_ls directory, then restart your editor
  • NOTE: This will cause you to have to re-run the dialyzer build for your project

If you're experiencing high CPU usage, it is most likely Dialyzer building the PLTs; after it's done the CPU usage should go back to normal. You could also disable Dialyzer in the settings.

Logs

1. If using a client other than VS Code, please try VSCode's "ElixirLS: Elixir support and debugger" extension. Does it reproduce your failure?

Yes

2. Create a new Mix project with mix new empty, then open that project with VS Code and open an Elixir file. Is your issue reproducible on the empty project? If not, please publish a repo on Github that does reproduce it.

As far as I can tell, this happens at seemingly random intervals when dependencies dont have a .formatter.exs file present. It works for a good while, then randomly crashes.

3. Check the output log by opening View > Output and selecting "ElixirLS" in the dropdown. Please include any output that looks relevant. (If ElixirLS isn't in the dropdown, the server failed to launch.)
