bug: unable to run iex command under macOS Big Sur

[d-ferenczi]

Hi Everyone,
I've tried installing a large number of Elixir versions of my system, but none of them works from asdf.
Command like iex or asdf exec iex return

exit status 1

The binaries themselves are functional, as a call to

.asdf/installs/elixir/1.19.4-otp-27/bin/iex

launches a working prompt.

I'm using asdf 1.18.0 on macOS Big Sur
asdf info returns:

Other plugins, including erlang work correctly.
I've tried reinstalling my plugins and asdf several time, but this didn't help with the problem.
Thank you in advance for your help!
