Radio/tape Cd Player problems of the 2019 Ford Edge

Rear view camera. The screen went to blue when I put me car in reverse. I backed out of driveway and put car in drive screen went black, then blue. When I came to stop sign the camera came on showing the street behind me. Started driving and camera stayed on while driving. Second stop screen went blue then black. Car is still in drive, proceeded on my way. Camera started flashing between blue, black and showing road behind me. This has happened 3 times once in April, this incident in June and once in August. I did reset to see if that worked and it did for a couple of weeks. With covid-19 restrictions. I am not doing a lot of traveling I can't duplicate it or why it happens, I thought maybe car had to be warm that isn't it. Just when it wants to do it. This also prevents me from using screen for radio or any other controls on the screen. I did report this incident to the dealership where I purchased my car, but never heard back from them at all.
