Cubase Logic Keyboard dimmer not working after 1909

I was wondering if anyone else has had this issue. I have one of the Logickeyboards Cubase/Nuendo backlit keyboards. Everything was fine until I did the WinX 1909 update then the 4 position dimmer stopped working. Not the biggest issue in the world, but it is annoying. Luckily it’s not stuck on the brightest setting but the next dimmest which is OK.

Tried driver update and nothing newer was available. Was thinking I might uninstall and re-install drivers.

Anyone else see this or have suggestions?
Thanks
