I use Nix to manage my development environment, and after updating the pinned nixpkgs version in a working project, without changing the pinned version of Elixir, ElixirLS started crashing on startup while compiling elixir_ls_utils. Is it likely something wrong with my setup, or is this a bug in ElixirLS?

The exception happened while checking this code:

end

Mix.start()
true = Mix.Hex.ensure_installed?(false)

case :erlang.function_exported(Hex, :start, 0) do
false -> nil
true -> Hex.start()
end

Mix.env(:dev)
Mix.target(:host)

for env <- ["MIX_ENV", "MIX_TARGET"] do
System.delete_env(env)
end

load_dot_config()
:ok
end

Hello!

Not sure what is the problem here, but indeed it seems to be a version problem.

Can you try to rm -rf .elixir_ls at the root of your project and restart your editor?

I had already removed that as well as _build and deps, to be sure no leftover artefacts were causing issues.
