How do I fix the issue with no video feed from VIOFO A129 Pro?

I have a VIOFO A129 Pro and when I power on it doesn’t show the video from camera. When I check my SD card on computer, it doesn’t have any file written to SD card.

I had this camera for a year and it was working at least until March this year when I checked last checked video stored in SD card.

How can I troubleshoot this? I have reset my dashcam before and it didn’t work.
