After the last system update, the IR sensor of the cameras stopped working, because of this application Photo Pro thinks that the camera is overheated and turns off after 5-10 seconds, in video mode and the Videogphy/Cinema Pro applications this problem is not observed, because this sensor is not there used, it is used only in photo mode. At the moment it is almost impossible to use Photo Pro, and I think that this is due to the latest system update.
