Windows Defender

I am unable to use my windows defender, whenever I open settings > privacy & settings, I am unable to open any of the windows security settings.

Whole Story - I have purchased new laptop HP Omen 8gb ram with GTX 1650 version, defender was working fine but later for reasons I completely reseted my new laptop and now I am unable to access windows defender, when I download and open app, it say 'liecense not found' even after having subscription. I am able to access apps like excel, powerpoint, etc except the defender and secuirty settings.

I request help as I am not able to access important feature of laptop.
