I'm able to reproduce this on Fedora 37, Emacs 28.2.

In Fedora we have:
- /usr/share/emacs/site-lisp/site-start.el (has code to load .el and .elc
from /usr/share/emacs/site-lisp/site-start.d).
- /usr/share/emacs/site-lisp/default.el (sets smime-CA-directory).

There are other patches but most of them are backports and seem to be
unrelated to package.el:
https://src.fedoraproject.org/rpms/emacs/tree/rawhide

Steps using with-emacs.sh (https://github.com/alphapapa/with-emacs.sh):

1. mkdir /tmp/emacs-59882
2. with-emacs.sh -d /tmp/emacs-59882 -- -l org
3. M-x package-list-packages
4. Install Org 9.6.1 from ELPA
5. When the package is compiled you get this error at the end (it is
there multiple times)
   ox.el:82:1: Error: Symbol’s function definition is void: org-assert-version
6. Close Emacs and start it again with
   with-emacs.sh -d /tmp/emacs-59882 -- -l org
7. I get byte-code: Invalid function: org-assert-version
