Set x-quit-keysym to nil in your early-init.el, then restart Emacs.
This feature (reinterpreting volume-down keys as quit) was introduced in
Emacs 30 to support computers without physical input devices capable of
typing `C-g'.

Incidentally, what keyboard are you using?  XF86AudioLowerVolume is not
generated by any I own, and x-quit-keysym is intended to only apply to
volume rocker buttons on mobile phones and their ilk.
