I ran a raw Emacs 29.4 with Hyperbole 9.0.1 and the minibuffer menu worked
fine without error.

The problem is that you are producing something from your keyboard that is
not a valid character that doesn't normally happen.  My guess it is related
to another package that you'll have to find and eliminate.  Try {C-h l} to
see what your prior keystrokes were before this gets triggered.  Does the
minibuffer menu fail in all cases for you, everytime you press normal
letter keys?  -- rsw
