Elixir `mix` command throws error `could not call Module.put_attribute/3 because the module Helloworld.MixProject is already compiled`

Setup new project with command mix new project_name it setup everything without any error or warning message, cd to project and ran command iex -S mix it throws error

enter image description here

lib/helloworld.ex

defmodule Helloworld do
  @moduledoc """
  Documentation for `Helloworld`.
  """

  @doc """
  Hello world.

  ## Examples

      iex> Helloworld.hello()
      :world

  """
  def hello do
    :world
  end
end

I was trying to install elixir on Rosetta terminal, and after switching to native terminal, was getting same error, so uninstalled everything related to elixir from Rosetta terminal, and on native terminal installed homebrew and followed https://elixir-lang.org/install.html#macos

Make sure all required dependencies must be installed with same homebrew
