Rear camera stopped working after screen replacement

Hi there,

I recently replaced my Pixel 6 screen. Since then, the rear camera stopped working. I tried a factory reset, which didn't solve the problem.

there is no error message when i wanna use it with the camera app or for example on whatsapp. the only result i get is a black screen, and sometimes, the camera app is crashing.

i didn't use any metal tool when replacing the screen, so no chance i could have damage the camera with a short circuit.

what could be the problem ?
