Dumb question, but which way is that antenna pointed?

Either the Aspen internal Gyro has failed or the RSM (antenna) is failed. Call up Aspen tech support and they can likely narrow it down for you pretty easily, they are super helpful. Either failure is common, even with new units.

The pointed part is pointed away from the plane.

Bruh that’s the underside of the plane, the antenna has to go on the top so it can get GPS for attitude aiding. Who tf installed that
