HTC 10 camera and flash doesn't work

Hi everyone,

I have an HTC 10 "Japanese variant" that did broke recently I did fix it but I forgot the password so I did a factory reset of the phone which is in Android 8.0.

After the reset everything works fine besides the camera and the flashlight which are inaccessible.

When I enter the flashlight app it just keeps loading and it's greyed out in the notification bar so I can't activate it nor tap it.

While the camera displayed once "unable to start camera" after that I just keep clicking the app and nothing happens, When I enter the selfie of the back camera it shows a report that I can choose to send or not to HTC.

I did check the connector of the cameras they're intact and also the camera.

I tried wiping cache, wiping data, wiping cache partition, factory reset nothing worked out.

I'm currently on 3.22.970.9, unlocked bootloader, S-ON and not living in japan but using stock firmware of the phone.

I would love to get some help with that problem it's kind of strange that both the front and back camera aren't working and the flashlight which is located in the motherboard.

Kind regards.
