Take-off behavior in Xbox Series X

A user is experiencing aircraft take-off behavior in Xbox Series X that
appears to be identical to that if mistakenly using the “Legacy” flight model
selection instead of “Modern” - but has sent a video of him clearly selecting
“Modern”, saving and applying, and then returning to the flight, only to have
the aircraft keep crashing on take-off. There haven’t been any other reports
of this from other users, and so am not sure what the cause could be. Have
suggested re-setting controls to default and then trying again, plus clearing
the Community folder and re-installing, but haven’t heard back yet. Any ideas
other than those?
