When I try to require elsa I get the following error:

I am running GNU Emacs 28.0.50, more specifically a commit from emacs-pgtk-nativecomp (https://github.com/flatwhatson/emacs/commit/11c956050b57c4a2e8b9a8186b22761ed752dc20).

Any idea what could cause this issue?

Probably some more changes in EIEIO. If I started this again I would definitely not use that framework, it's a *%^$*ing pain.

Thank you for the feedback, I will try with a different version to see if we can pinpoint this.
