Some key commands quit working in Dorico 4.3

A few of my key commands no longer work after I updated today. They are still listed as key commands page and in the jump editor. Two I use frequently [1] call up the graphic slices editor (ctrl shift g) and [2] return to the general graphic editor from the frame/system/note spacing editor (g). I can’t remember if these were custom or standard key commands. Ideas?

PS
It’s always a good idea to do a quick search before you post - there was already three threads about faulty key commands since the 4.3 release - it’s helpful to have everything in one place.
