Same 13.7 upgrade, Xcode 14.2. Cmd+left, Cmd+right work(!) To me it is subword move related Ctrl+left, Ctrl+right, Ctrl+Shift+left, Ctrl+Shift+right. Colliding system settings >> keyboard >> shortcuts for Mission Control (those without the Shift) are disabled. When I launch Xcode from the terminal as /Applications/Xcode.app/Contents/MacOS/Xcode, I get this output from start and when visiting Settings >> Key Bindings NSKeyBindingManager: Bad key binding atom for '^' = 'moveSubWordBackward:' NSKeyBindingManager: Bad key binding atom for '^' = 'moveSubWordForward:' NSKeyBindingManager: Bad key binding atom for '^$' = 'moveSubWordBackwardAndModifySelection:' NSKeyBindingManager: Bad key binding atom for '^$' = 'moveSubWordForwardAndModifySelection:' Settings >> Key Bindings sees conflicts and hints "System shortcuts may take precedence over this shortcut", without telling which particular system shortcut. No solution yet.
