Windows 10: Windows 11-Cannot turn down brightness after update

All of a sudden I cannot turn down the brightness on my laptop. The little bar shows that it is going down, but the brightness doesn't actually go down. I checked the drivers and they are showing as being up to date. Only the volume slider works.
