My Redmi note 12 Camera is done

My Redmi note 12 Camera doesn't work anymore, I tried everything, the repair shop said it's a hardware problem, and they can't get inside a Redmi, it was also Brand new, One day before the camera completely stopped working, I saw fog, inside the camera when I woke up,

I think there is a small plug that got loose, The flash is also Not working, So No camera and no flashlight. I just wanna go inside the phone, and connect that loose wire that I think is the problem, Anyone have an idea of what it might be ?
