I have somewhat found a work around. Please note, this may only work for certain people and that I also have a brand new radio head unit and camera that was installed yesterday, 6/12/2021.
I woke up this morning and noticed the camera was indeed working. Got to work and 3 hours later when I went to go pick up lunch, the camera went out again. I reset the radio to factory defaults, clearing the default applications and user settings (there are 3 reset settings in the radio settings menu). I then put the truck into reverse, and the camera was back on.
All I did this morning after I noticed the camera was working was connect my iPhone 12 Pro Max to Apple Car play to listen to my music. Not sure if that was what caused it, but I will keep investigating if the camera decides to go out again. With all of that being said, it is most likely just a software bug. I guess working in I.T. pays off a little bit. Maybe I will try just using standard bluetooth instead of CarPlay to see if that still causes it to go out. Or maybe it isn't related at all....IDFK.
