Korg nanoKONTROL2 and Cubase12 no longer works properly

My Korg nanoKONTROL2 no longer works properly. After the update, Cubase recognised my controller. I can assign all keys and functions and in the MIDI remote window the keys also work when I press the keys on the keyboard. The problem is that I have no direct reaction from the controller, no key works. The controller runs on Windows Midi channel 2. KorgKontrol-Editor and MidiDriver are newly installed. My Vst’s work as usual with the controller and all keys are also learnable. With Cubase, the learning ability of the keys does not work either.

MIDI events which relate to MIDI Remote bound controls will not be routed through to MIDI- or Instrument tracks. If that is an issue, you can disable the nanoKONTROL-script in the MIDI Remote Manager window.

Or maybe you just have to close the MIDI Remote Mapping Assistant window.
