iPhone 8 rear camera not working

I have had my iPhone 8 for a while. Never had any issues with it. All of the sudden my rear camera does not work. I have done all of the normal stuff that you do when the iPhone has a glitch Such as reboot, restart, restore, restore like a new iPhone, restore from the iCloud back up, DFU restore LOL you name it I have tried it. I am pretty tech savvy. I’m thinking it is a hardware issue but wanted to check here first before going to apple.
