Audio MIDI Set Up wont load

Hi - I've been using logic for a few years now. Three days ago I whilst opening it, a pop up said MIDICORE was not working and I haven't been able to fix it since.

I read online that booting up in safe mode + opening audio MIDI set up would fix it, thing is audio MIDI set up wont load up.

Anyone knows how I can fix it? I am on the verge of tears as I cannot seam to find any information online about audio MIDI set up not opening. And I cannot seam to fix the MIDI issue without it.

Thanks!
