Camera not longer working after unlocking Bootloader D6633

Has anyone encountered this problem? I have Unlocked my Sony Z3 Dual D6633 and rooted successfully, once I unlocked it, the camera stopped working, just show black, even the front camera
Have tried other apps, like Google camera but still the same

I understand that losing the DRM key could affect the camera quality but, it;s now totally broken :(

Any advise please?
