Midiproblems Musescore 4

Midi inputs have stopped working for me. It worked fine the day before yesterday. I have tried to restart the computer, restart the program, plugged my midikeyboard in and out, gone into setting and deselected the keyboard and afterwards reselect. I can see that the program recognizes my midikeyboard when I plug it in. It does not matter which project I'm in. The keyboard is turned on.
