Did not work in the sense of resolving the original issue of this bug
report:

Invoking (push '(fullscreen . fullboth) default-frame-alist) during
Emacs startup causes it to hang, no matter where it is, early-init.el,
init.el or passed through --execute. Same goes for
(toggle-frame-fullscreen) and everything else that makes Emacs switch
to fullscreen mode.
