ElixirLS crashing in vs code with umbrella project

[beardedeagle]

I am getting the following when opening VS Code Insiders with the Elixir LS plugin installed:

Hrm. I nuked all dialyzer files in .mix and in my project, removed deps and _build then rebuilt and opened everything from the umbrella project root and now I see data populating Problems. I'll leave this open in case you want to look at it.

[JakeBecker]

Hm. I don't know, but I recommend that you don't run both vscode-elixir and vscode-elixir-ls extensions at the same time. Both will try to compile your project code and they're likely to interfere with each other. I don't know if that's the cause of your issue, but it'll likely cause instability of some sort.

@JakeBecker Hrm, I'd agree if it weren't for the fact that this operates as expected with non umbrella apps. This issue literally only occurs in umbrella apps. Would be great to see support for it. May I recommend reopening the issue until it can be looked at closer?
