Thanks, but why do you think the bug is in Emacs and not in vertico?
The fact that you can unfreeze Emacs with C-g indicates that some Lisp
is involved in what probably is an infloop.  At the very least, could
you please catch a Lisp backtrace when you type C-g, so that we could
see what Lisp is involved?  Also, what exactly does vertico do with
resizing the mini-window, and what should be the value of
resize-mini-windows for reproducing this issue.
