Can it happen that already loaded version affects compilation of a new
version by package-install.
Yes. It is what appears to be happening:

I would not call it steps to reproduce.
From my point of view, there is a number of issues with updating of
packages from emacs session.
1. If compilation of a package failed then it is not withdrawn from the
load path.
2. There is no reliable way to determine if package compilation failed.
(byte-recompile-directory DIR 0 t) returns human readable string, not
signalling an error or returning a value convenient to check in the
code. It is the cause of the previous issue.
3. Emacs package system is not ready for complex multifile packages
containing macro definitions. It does not push user to update packages
just after emacs restart in a clean state. As a result, files may be
compiled with old or missed macro definitions.
4. Because of the item 2 a package has no chance to implement reliable
internal sanity check that prevents updating to a broken state.
I have tried the following in Emacs-27. For Emacs >= 29 add -L to Org <=
9.5.
- "emacs -l org" to simulate a regular user session with some opened files.
- Update to Org-9.6 from ELPA.
- Close emacs and start it again "emacs -l org"
Result:
byte-code: Invalid function: org-assert-version
Notice attempt to load Org-9.6 despite warnings and even error during
update:
Compiling file /home/emcs/.emacs.d/elpa/org-9.6/ob-C.el at Sun Dec 18 04:30:49
2022
Entering directory ‘/home/emcs/.emacs.d/elpa/org-9.6/’
In end of data:
ob-C.el:509:1:Warning: the function ‘org-assert-version’ is not known to be
defined.
...
Compiling file /home/emcs/.emacs.d/elpa/org-9.6/ob-matlab.el at Sun Dec 18

ob-matlab.el:43:1:Error: Symbol’s function definition is void:
org-assert-version
So emacs can not handle update of a package with changed macro
definitions when they reside in another package file.
