Cameras Just stopped functioning on iPhone 13 Pro Max

I have been uses my cameras like normal but I have had this issues where my back camera states that its not the original part even tho I have never taken it to get opened or fixed at all. I was told at the Apple Store that I just need to reset it and it should work but that was never the case no matter how many times I reset it, it never worked. The 0.5 camera featured stopped working but it didn't really bother me. But today all day the cameras were working fine and all off a sudden they just stopped working I kept reseting and reseting it but to no avail. I had noticed that in every attempt of using the back cameras the region to the right of the cameras would get hot pretty fast. I wonder if its either a connector issue or a motherboard issue.
