Logic Pro input selection not working

I can no longer select an input from my audio interface (Native Instruments Komplete 6 MK2) since today. Yesterday, all was working.

I Did the latest Apple Update over night. (Macbook Pro 14inch, M3 Pro, 18G, macOS Sonoma Version 14.2 (23C64)).

When I try to select an input, the channel always uses input 1.

Driver, firmware of the interface is latest version.

I deleted Logic and all settings files etc and reinstalled.

Nothing seems to change the problem.

The audio interface works fine in Ableton Live and Garageband.
