Error when trying to start project's process

[rockneurotiko]

I'm in today's nightly build (January 15th 2026), and I have this error whenever I open any project with expert:

This lookalike your local build of OTP is missing or not loading the public_key application.

What version of OTP are you using? What OS? How'd you install it?

[rockneurotiko]

That's weird, because it used to work and it stopped working around january 14th or 15th.

My details:

OS: Archlinux
Elixir and Erlang installed with mise, with this .tool-versions

erlang 28.3
elixir 1.19.4-otp-28

Erlang/OTP 28 [erts-16.2] [source] [64-bit] [smp:32:32] [ds:32:32:10] [async-threads:1] [jit:ns]

Elixir 1.19.4 (compiled with Erlang/OTP 28)a

[rockneurotiko]

I installed erlang-public_key and erlang-ssl from the arch repository and it worked, but it should be using the mise binaries and not the system binaries right? Is it not supported?

Edit:

The timeline on when it stopped working for me matches with this PR that changes things related with mise: #304
