It looks like elixir-ls don’t even started. I don’t use vs code but maybe you could try to clone and build elixir-ls locally. It is in this repo GitHub - elixir-lsp/elixir-ls: A frontend-independent IDE "smartness" server for Elixir. Implements the "Language Server Protocol" standard and provides debugger support via the "Debug Adapter Protocol" · GitHub, for starter maybe just try deps.get, compile and iex -S mix. Maybe even details about your laptop like os and architecture can be useful, If I remember right, vs code elixir-ls plugin is boundling already build version of elixir-ls.
