Problem with Portrait Mode

I know. Earlier it was perfectly working on both cameras. now it doesn't work on main camera.

when I am in selfie camera, I can change the light etc.

but when I'm on main came, I don't have this yellow effect ( "When Portrait mode is ready, the lighting effect, like Natural Light, turns yellow."). it's like inactive

Maybe I am not describing the problem correctly.

The portrait mode doesn't "load" when I turn it on, when on main camera.

when I switch to selfie, it works and takes pictures in such mode.

when I am on main camera it takes normal photo, like in "normal" mode. No effects, no blurred out background, basically it is not working at all on main camera. And I am trying to find out why

Nothing. Thats the problem. I see the screen like its in normal Photo mode. But with portrait options. But they all are greyed out. Switching light etc doesn’t change anything.

i see portrait mode options.

but if put my finger it doesnt ask me to put it further. It doesn’t „read” that I turned into portrait mode. Everything looks like normal mode but with portrait options

Tried. It just doesn’t „load” to portrait mode when i switch to it from „normal” mode
