Few days after firmware update (4.32) when camera's turned on the mechanical shutter opens and closes for 3 times (by itself), a message comes on the screen 'turn off the camera and turn on again' and camera doesn't respond to any button. When is turned off mechanical shutter opens and closes once again. The last pics taken before that were unreasonably overexposed, while there was a pic with half shutter covered (black)Please help VID_20200427_193731.mp4
