If you just start a fresh session, save its desktop, then restart it,
while using the lazy-load feature, does it start normally? Maybe all
that's needed is to do this, with no personal files involved.

Thanks.

Does Emacs crash when restoring a desktop file written by Emacs 24.5,
or only when it restores files written by Emacs 25?
