Feel free to first try a IMU calibration, but... this looks to be way more than what a simple calibration can solve... the most troublesome is highlighted in bold, looks more like something have disconnected from the Flight controller. Either you carefully lift off the outer shell of the drone & inspect all connections & soldering's, maybe you can spot something obvious... or send it in for a repair.
