Rear Camera and Flashlight Not working.

Hi, I replaced the screen and battery on my pixel 8 pro and everything is working fine except for the rear camera and flashlight. Inside the camera app it just says something wen wrong. I have ensured that all the rear camera cables are plugged in but still nothing. I have tried seemingly everything from google so I was wondering if anyone knew what could be happening. There is no visible damage to the rear assembly, cables, or motherboard. I am at a loss here so any help is greatly appreciated. Thanks!
