CoreMIDI crash problem solved (logic, cubase, garageband etc)

I had the same problem as some other users with CoreMIDI and contacted apple support, after random troubleshooting solutions this is what worked:

restart mac in safe mode, open whatever daw you are using. Than restart in normal mode solved it for me

here's how:

Start up your Mac with Apple silicon in safe mode

1. On your Mac, choose Apple menu > Shut Down. Wait for your Mac to shut down completely. ... 
2. Press and hold the power button on your Mac until “Loading startup options” appears.
3. Select a volume.
4. Press and hold the Shift key, then click Continue in Safe Mode.
