Screen brightness is not changing

I have a brightness control on my keyboard and it is not changing the brightness. I've tried manually adjusting it through the settings on Windows 10, but I do not see a slider. The nightlight setting also doesn't work. All drivers are up to date and did not have this issue until I reformatted my computer.
