Does your integrated terminal in vscode have the necessary envs? I guess thats what vscode uses to launch elixir-ls

Try a local user install as described by asdf rather than some package manager that installs system wide.

Thanks @NobbZ
Installed asdf again from sources –not using brew- and it works smoothly.
@lukaszsamson my integrated terminal is zsh and loads every other terminal outside of VSCode.

Hello,
I am using VS Code via Windows 10/WSL (erlang/elixir installed via asdf) and I also get
Failed to run ‘elixir’ command. ElixirLS will probably fail to launch. Logged PATH to Development Console.
I even do not know where/what this “Development Console” is (google didn’t help).
Is someone able to help me?

@Facundo I can confirm that! Just <upgraded> my MacBook Air M1 to BigSur - and the next thing I noticed was that ElixirLS fails to start in VSCode
my .zshrc is good as is my asdf local elixir 1.12.0
I may have installed asdf with brew first - but my current installation is tucked away safely in $HOME/.asdf 
Tried iex from CLI only to learn that elixir wasn’t the issue at all - erl was! (Note: I run all my workbench stuff in containers which is probably why I haven’t noticed)
Once I got my asdf global erlang 24.1 out of the way - all was good in VSCode on macOS BigSur land

Actually, “development console” in that error refers to Chromium’s Electron’s VSCode’s development tools console, which is under the Help menu header on MacOS, and… might be in a similar enough part of the Windows menu if you dig around for it a bit, @Nefcairon.

This ended up being the solution for me here on Groundhog’s Day, 2022. I forgot to set my global erlang asdf.
Rectified, relaunched, resplendent.

Setting erlang and elixir globally solve the issue for me as well
asdf global erlang <your_version>
asdf global elixir <your_version>

I solved it using:
sudo dnf install erlang-dialyzer
sudo dnf install erlang-edoc
asdf local elixir 1.13.3
asdf local erlang 24.3.4
