UA Apollo Twin shows signal at interface but no signal

The App was working fine recorded Bass and Guitars using Apollo twin yesterday, today I can't get any signal from interface to MPC software.

I can monitor the sound at UAD console so I know sound is present, I haven't changed anything.

any help getting my guitar signal from Apollo to the Audio Track would be greatly appreciated. Ive googled and spent hours trying to fiddle with the cause. I kinda feel like it's a software solution(like a setting that I need to change) issue. Im new to this software so it could be a simple solution that I'm just missing.

I ended up installing a previous version and everything worked as it should. Then I updated back to the latest version and everything seems to be working fine.
