Finally, I found some reproducible example.
straight.el redefines some org functions before loading org.
It is done in straight--fix-org-function (org-git-version and
org-release are redefined). 
The redefined version works with org.elc, but somehow get overridden
when org.eln is loaded (in my case, the loading is triggered by elfeed-org).

Steps to reproduce:

1. Use the attached file to load emacs. No errors should appear.
2. Wait until org is native-compiled.
3. Restart emacs. The following errors appears
(straight--fix-org-function supposed to be a workaround for this error):

Error (use-package): elfeed-org/:catch: Invalid version syntax: ‘N/A’
(must start with a number)

4. Delete org.eln
5. Restart emacs. The error disappears.

Best,
Ihor
