I had a similar issue on my windows work computer. In the keyboard layout "C-M-e" was translated into '€' . I simply rebound '€' to be forward-defun as I don't type that ever, and if I for some reason wanted to I guess I could do "C-q €"

I noticed this as well after moving to emacs 29. Turning on pixel-scroll-precision-mode fixed it for me.
