".credo.exs file does not exist" in Umbrella project using VSCode extension

Background

I have an umbrella app with the following structure:

:.
├───mix.exs
├───.mix.lock
├───.credo.exs
├───apps
│   └───app1
...

When working with my umbrella project, I usually open the root folder of the project and work in the desired application from there.

My .credo.exs. file is the default one generated by mix credo gen.config and I have {:credo, "~> 1.6", only: [:dev, :test], runtime: false}, in my root’s mix.exs file.

I have also installed credo and its dependencies using:

mix archive.install hex credo
mix archive.install hex bunt
mix archive.install hex jason

So I am sure I have all the dependencies installed.

I also launch VSCode with code . using Windows cmd to make sure I get all the ENV vars from the shell loaded.

Problem

The issue here is that no matter what I do, I always get the .credo.exs file does not exist. Ignoring .... no matter what I do.

To try and fix my issues I read this post:

However this wont do it for me. Not only do I still get the error once I get inside the individual applications, it also does not fit with my workflow, as I mostly work with the root directory open.

Questions

How can I fix this?
