Zenfone 5Z Main Camera Issue

[japp]

Hello,
Did anyone experience recently any issue with the camera?
It takes ages to load and sometimes it is stuck in black screen, when I want to scan qr it just freezes and does not allow me to do anything.

Front Camera seems working fine, specially when I am required to take selfie for some apps.
I tried stop camera, reset cache and delete files, reboot, and even now factory reset.
I am like 8 out 10 attempts does not work.

I am running with latest Jan 5 2021 security patch and Software WW_100.10.107.123_20210131, but issue appear way after I did upgrade, so I do not suspect upgrade issue.
