Any ideas why keyboard stopped working under Gnome on Wayland?

The keyboard suddenly stopped working under Gnome on Wayland.
That is the internal keyboard of my notebook as well as the Screen Keyboard.
The keyboard works fine when I switch to Gnome under Xorg though.
This is Fedora 37 on Intel Graphics with latest updates applied.
The issue persists also after a reboot.
Any ideas how to fix this?
