BackUp Camera Question

Anyone else have consistent problems with their backup camera? June marked 3 years with my '22 Evoque and for the 3rd time my backup camera has stopped working! It hasn't worked at this point in over 6 months because the dealer never answers the phone, but the camera clearly works on the rearview mirror camera, and the beeping sensors work just fine but a red slash through the camera anytime I'm in reverse... SO annoying!
