Cubase artist 9.5 randomly isnt detecting audio out from my apollow twin

I am new to the software

it was working fine I could record and play back thru my headphones connected to Apollo twin

went to play something back a few days later and it was just playing out of my screen speakers…

I looked through and it says in yellow writing “audio output not connected” in the tool bar right above project window.

I went into studio found where it says audio output tried to connect to Apollo but when I click “connect to Apollo twin usb” it doesn’t do anything

PLEASE HELP!! :smiling_imp: :imp:
