Front cam black screen / disabled flash / cooldown error

hello friends,

I am having a problem with an ipad 9lte.

the charge port got broken. I replaced it but then when I tested it, the front cam was not working. it gives an error with flashlight and full black screen. The back cam is fine.

I tried different front cams and back cams. nothing changed.

I am adding 2 photos. one is marked with pins on the front cam connector. 5-6-7-8 are giving OL , I am just curious if you have a board can you measure for me? Also the other picture that I need is a place where I think is a problem. I need a picture of that area for conparison.

edit: sorry I forgot to ask the question :) what is causing this issue? Has anyone exprienced this?

Thank you so much.
