Omega B – FL door opens suddenly while driving

While driving through a pothole, the driver’s door jumps up. This happens regardless of the locking state. Can it actually only lie at the lock position opposite the catch hook or at the adjustment screw of the actuation rod from the lock in the door or? Has anyone ever had this ? In a right turn this happened to me and the door almost completely ripped off at 50kmh. No car experiences! Incredible! If someone comes to meet you, the simply omega door gets in the headlight.
