I think I know what is causing the problem.
If it happens again, you have to quickly flick your controller to Sport mode, and then you can force the drone to come back.
It happens because the internal wiring for obstacle avoidance cameras have become lose, so the GPS data becomes unreliable and that's why the drone malfunctions and drifts off, and refuses to respond to controls.
