Disappearing mixer Cubase 11

Loaded a backup whilst in the middle of a mix because some of the mixer history was definitely incorrect. I then went back to the original mix and It loaded up with the tracks in the project window but nothing in the mixer and wouldn’t play any audio. Had to restart Cubase.
Anyone else had this? What gives? It’s a £500 piece of software.

You probably didn’t activate the project. Activate it by hitting the lightning icon (top left of Cubase window), and the mixer will appear. It only shows for the active project you see.

CZFred, entirely possible mate, cheers.
