iPhone 11 back camera/flashlight not working

earlier today when i went to go on my phone, the camera was making weird, clicking mechanical noises. those stopped and now my camera and flashlight aren't working. i can use the front camera but whenever i try to flip it to the back.. it's just a black screen. ive tried trouble shooting in every single way possible but nothing has worked. turning off my phone and back on, switching off the camera app in content & restrictions, i cleared some storage, etc.. it also won't work on any other app that i have. nothing has worked, any other solutions?
