Starship has already reached orbit many times but places itself on a suborbital trajectory to intentionally test re-entry and landing which it has done successfully several times.
LOL. Are you serious?
To reach orbit: to reach a horizontal speed such that the spacecraft can complete a revolution around the celestial object while in free fall, without having to execute any additional maneuvers.
Starship has yet to reach orbit. The reason doesn't matter. It hasn't done it.
