Logic not picking up audio

I simply can't record/get playback on Logic. It's not a hardware problem since I can do it on other apps. If I set the input to Internal Microphone for example, no audio gets received. It's only been a problem since I updated to Mojave but I don't think that's the reason for it. I'm sure I accidentally clicked on the wrong thing at some point, what could be the issue here? It's also up to date.
