greetings stefan..

i just pulled down a recent release of emacs (
https://emacsformacosx.com/emacs-builds/Emacs-29.1-1-universal.dmg),
started with `~/Downloads/Emacs.app/Contents/MacOS/Emacs -q`, and the issue
is still there.  are you using magnet?  the default bindings of
ctrl-opt-leftarrow or ctrl-opt-rightarrow (using mac keyboard nomenclature)
to move the window to the left or right of the screen don't work.  if i
type ctrl-opt-x, the minibuffer reports "C-M-x is undefined", but doesn't
say anything when i type ctrl-opt-leftarrow or ctrl-opt-rightarrow.  again,
this does work with the railwaycat build (and the 15 other mac apps i have
open).

i just verified i don't have any global shortcuts defined by going into
system settings/keyboard shortcuts and defining ctrl-opt-leftarrow to show
notification center.  it doesn't show a conflict with any other shortcuts,
and it overrides the magnet binding and shows notification center.
