OK.  So the interactive session starts as expected, whether you invoke
Emacs by "emacs" via PAYH or by its explicit absolute file name
/usr/local/sbin/emacs-28.0.50/emacs-28.0.50 or by going into
/usr/local/sbin/emacs-28.0.50 and typing "./emacs", right?  So I think
there's progress.

I will see what can be done to understand why async-start fails.

In any case, what error messages do you see with async-start now? can
you show those messages in their entirety?

Thanks.
