To be precise, I am surprised that you are unable to reproduce the issue 
with older Emacs version compiled from source.

I have no clue why your patch should help in this case.

My hypothesis: the user has `use-package' org-roam in their init file. 
Attempt to update org caused compiling new org when old version is 
already loaded due to Emacs-27 does not contain fixes that reload 
package that is installed. Next time load of org failed because it is 
result of mixed version compilation.

I am not sure. Perhaps it should be (or (fboundp 'org-assert-version) 
(new-package-management-code)). Since testing for private function is 
not a reliable solution, only version check is available.
