MIDI Devices do not work

Hello.
My midi devices don’t work anymore. Not sure if this happened after a Windows update.
Both in Cubase 11 and Nuendo 11 i do not recieve any Midi signals from m,y Akai MPD18 or my Komplete Kopntrol s49, and also my CC121 doesn’t work anywore, only the cubase ready light is blinking.
I can not re-add the cc121 in the studio settings, it dosn’t show that device in the list.
I updated all the drivers as well as Cubase/Nuendo.
In the MIDI Settings all my midi devices are not shown, allthough they are shopwn in my windows device manager.
what the hell is going on here? I can’t work like this!

Hi,

Could you try in the Cubase Safe Start Mode [Disable preferences], please?

I tried that, it didn’t help.
It might me a windows issue…when i open a standalone instrument like the FM8, Midi doesn’t work eather…
