Cameras not working after changing battery.

Hello guys,

I have a problem with my iPhone 13 Pro.

I successfully (more or less) swapped my battery with a new one bought on iFixit.

After reconnecting the battery, screen, etc., I noticed that my main cameras are not working at all, I can only see black screen in camera app, and any other app that uses camera. selfie camera worked for cca 10 minutes, and then it stopped as well. After a reboot, selfie camera works again, but main cameras do not.

Flashlight does not work as well.

Face ID works normally.

Any ideas? I was very careful not to damage anything while changing the battery, everything went smooth actually.

Thank you everyone on suggestions.
