Hi, I have a problem with compiling a project on my Mac. I’m experiencing the problem through all branches that were originally executable and no changes were made to them. Suddenly everything stopped working and I honestly have no idea what action could have caused this problem.
== Compilation error in file lib/my_app_web/controllers/user_switch_role_controller.ex ==
** (ArgumentError) defdelegate function is calling itself, which will lead to an infinite loop. You should either change the value of the :to option or specify the :as option

On my friend’s Mac everything is working fine. We both have a Mac M1 with OS Ventura 13.2.1. I can compile the same project on a Linux virtual machine without any problem.
Tool versions:
erlang 25.2.3
elixir 1.13.4-otp-25
nodejs 12.22.12
Steps I tried.
- Uninstalling Elixir, Elrang and NodeJS, then the whole asdf. And then installing asdf and reinstalling Elixir, Erlang and NodeJS via asdf.
- Reinstalling xcode.
- Clone the project to a new folder
This is code from controller. Only def action.
defmodule MyAppWeb.UserSwitchRoleController do
use MyAppWeb, :controller
use Filterable.Phoenix.Controller
alias MyApp.Users
alias MyApp.Users.User
def edit(conn, current_user, %{"id" => id}) do
user = Users.get_user!(id)
live_render(conn, MyAppWeb.UserLive.EditOwnRole, session: %{"user" => user})
end
def update(conn, current_user, %{"id" => id, "user" => user_params}) do
user = Users.get_user!(id)
case Users.update_user(user, user_params) do
{:ok, user} ->
conn
|> put_flash(:info, gettext("User updated successfully."))
|> redirect(to: Routes.user_switch_role_path(conn, :edit, user))
{:error, %Ecto.Changeset{} = changeset} ->
render(conn, "edit_own_role.html", user: user, changeset: changeset)
end
end
def action(conn, _) do
args = [conn, conn.assigns.current_user, conn.params]
apply(__MODULE__, action_name(conn), args)
end
end
I have defdelegate elsewhere in the app, but when I went through them, none of them even refer to the controller.
If it was explicitly a code error, wouldn’t it show up on a second Mac with the same setup?
Error def is here:
Anyone got any ideas? I would be glad for any help. 
Thanks.
