Ok, that’s fine! I’ll try it!
Edit: I do got the elixir/erlang binaries to work using the erlang 26, however it seems that the elixir-ls binary stills seem to be broken even on the last release 0.16.0:
running /nix/store/2i4xqwk4g0zk39dik4qvk0gsv0nqxbg2-elixir-ls-0.16.0/bin/launch.sh
Preffered shell is zsh, relaunching
Looking for ASDF install
ASDF install found in /opt/homebrew/opt/asdf/libexec/asdf.sh, sourcing
zsh: bus error elixir-ls
Looks like there was an issue I nixpkgs as well (erlang and elixir broken on macOS Sonoma · Issue #257880 · NixOS/nixpkgs · GitHub)
I’ve created a seperate issue for beam packages, since there is no workaround for those: Beam modules throw `bus error` in aarch64-darwin on macOS 14 Sonoma · Issue #258100 · NixOS/nixpkgs · GitHub
Same problem until i disabled jit with this. along with comments here. How to install Erlang and Elixir on macOS with Apple M1 Chip — DevHeroes

I’d suggest compiling elixir-ls yourself for now
MIX_ENV=prod mix elixir_ls.release -o ~/.local/share/elixir-ls/
I believe it’s mix elixir_ls.release2 nowadays, or at least that’s how I’ve been building it for a while now.
For anyone else who just upgraded to Sonoma and are having the same issues re-installing Erlang < 26 I found a workaround here OTP25 bus error on Mac OS Sonoma · Issue #7687 · erlang/otp · GitHub
For those who uses nix you acn easily override the configure flags for the erlang compiling, as I show in this example to make elixir-ls work again:

I also add another solution for this.

In my case a simple brew upgrade; brew update resolved the issue. Running Elixir 1.15.6 on OTP 26 on a M1, 2020.
I also got hit by this bus 
Thanks all for your tips, in my case, I fixed it with:
brew upgrade
export KERL_CONFIGURE_OPTIONS="--disable-jit"
asdf install erlang 25.3.2.6
As in OTP25 bus error on Mac OS Sonoma · Issue #7687 · erlang/otp · GitHub
Everything is running fine now!
