Camera not taking photos or videos.

My Vision 2+ camera sends good video feed (FPV) to my iPad but the camera will not take photos or videos. It has worked fine for about 6 years and then stopped taking photos and video, yesterday. No crashes or even rough landings. I swapped SD card with new one. Formatted new one. Upgraded firmware. Still just get error message when I try to take photo or video and it just returns to video feed
