The thrusters that turn the craft around and allow precise movement aren’t working properly, they barely got the thing to dock with the ISS.
Despite what nasa says publicly, I’m sure there’s a lot of internal debate about if it’s even safe to undock the thing from the station. If it loses orientation control while still close to the ISS, it could easily damage the station and kill people. That’s if some of the damaged thrusters aren’t the ones that allow the craft to go backwards, kind of important if you want to leave the station.
