Brightness no longer changing after update

I did an update on June 3 listed as KB4503864 and after that update, I can no longer change the brightness on my Dell Inspiron 15 5000 series laptop.

I have looked around at how to fix but nothing is working. Is there some sort of patch that can be down in order for this the brightness to change again?

 

Change screen brightness

My laptop screen is dull. Need to make it brighter. However the suggestion --> Start - Settings - System - Brightness and color

does not work. It is already set to max. brightness but there is no reaction. Screen remains dull. By the way there is no change if I move slide to minimum brightness, it would not change brightness level at all. Any suggestion?
