Dorico through headphones only plays Left channel

I’m on the latest version of Dorico and the latest version of MacOS. I don’t often use headphones in Dorico, but I’m trying to now and I only have audio coming out of the left channel. The headphones work fine. I restarted but to no avail. The panning slider is in the center.

TIA

Please create a new project from solo piano template, enter a few notes and reconfirm that only left audio comes out. Then do from the Dorico menu Help > Create Diagnostic Report which creates a zip file on your Desktop. That zip file please attach to a reply here. Thanks

Thanks. I did that but it’s working on that new file I created. I also checked other files and they work as well. It seems to be just this file. Where should I look that’s causing the problem?

Maybe this?

Thanks, I appreciate your help. It turns out that somehow the L/R control on my Output fader was set to L100, so I set that to 0 and everything is normal now.
