Working on my 8.11.1. Stable sucks anyway.
You can try with manual build.prop edits:
persist.vendor.camera.enableAdvanceFeatures=0x347
camera.disable_zsl_mode=false
You'll spot these easily.
I added the full stack of 8.11.6 night mode cam with libs as flashable zip on my Drive.

So with these files, "Fix-by-Pixel" is not required. Freeze after two pics is gone, etc.
"Fix It...of don't Fix with next release i downgrade to 8.8.30"
If ... else I will ... (although with typos and insufficient English skills) is the prototype definition of threatening.
