Apollo Twin, no input level or sound

Hi Everyone,
I can’t get seem to get any input level when I plug my guitar into my HiZ on my Apollo twin. My inputs and outputs are set, but now I have no sound what so ever. Am I missing something? Do I have to do something in console first? I just upgraded from 8.5 and everything was fine. I have Luna and that still works. I jump between the two DAW’s because there’s stuff I can’t do in Luna yet that I need cubase for still.
Any help is greatly appreciated. It’s been a VERY LONG TIME since I had to set anything up in cubase.

Hi and welcome,

Are you on Mac or Windows?

If you are on Mac, make sure Cubase has enabled Mic in the System Preferences, please.
Open macOS System Preferences > Security & Privacy > Privacy > Microphone. Enable Cubase here.
