Yes.

You will find the code in async-start function in async.el
https://github.com/jwiegley/emacs-async/blob/master/async.el#L296

No, unfortunately it is really hard to get error messages from async.el.
These message came from calling ./emacs or ./emacs-28.0.50 from
/usr/local/sbin/emacs-28.0.50/.
However if it may help, it seems the process buffer is created, and then
the process (emacs) never start, here the contents of the "*emacs*"
buffer (emacs started with "./emacs" from /usr/local/sbin/emacs-28.0.50 directory):
