Short description of error there is no reason to have changed this shorcut so I imagine that its a mistake
Exact steps for others to reproduce the error go to pref and turn alt+ctrl+g to alt+g like alt to invert an action
Based on the default startup or an attached .blend file (as simple as possible).
