I have had DJI MINI 3 PRO for a few days now. A few days ago, an unpleasant problem appeared, but after unplugging it from the charger, the drone seemed to stop flying for a moment. Below are photos with errors that prevent the drone from starting. I will add that I cannot perform calibration, the gimbal stops at 0% and a calibration error appears, and the IMU does not respond after pressing START.

Hi there. Our sincere apologies for this unpleasant experience. Kindly please try to restart the aircraft and check if the issue persists. If yes, I'm afraid that you may consider sending the unit in for a proper diagnosis. You can reach out to our support team to start up a ticket at https://www.dji.com/support or contact the dealer where you purchased the unit for further assistance. We appreciate your understanding and support.
