What happens if you invoke Emacs like this:

  emacs -Q -fn Input

I suspect that Input font is not good for Emacs, so it rejects it.

Nevertheless, I think the definition of
dictionary-word-definition-face is problematic: it shouldn't use font
names such as "default", because it will always fail like this:

> Debugger entered--Lisp error: (error "Font not available" #<font-spec
>   nil nil default nil nil nil nil nil nil nil nil nil ((:name .
>   "default") (:user-spec . "default"))>)
