Dorico 4 and Note Performer no audio Windows 11

I recently switched from Mac to Windows and installed Dorico 4 on my new computer a few days ago. However, the audio on Dorico has not been working for both Note Performer and the stock Halion sounds. The playback seems to work, but there doesn’t seem to be any sound coming out of Dorico at all (the mixer shows no audio being played). I completely uninstalled Dorico and Note Performer, but the problem persists. Has anyone had a similar issue, and what were the fixes? Thanks.

There’s an audio troubleshooting video from Dorico:

[No sound issues are very common. I think there’s a page on the forum with further audio advice but I can;t find it right now.]

Welcome to the forum @sfc3.
If you still cannot get sound out, please create a new project from piano template, enter some arbitrary notes and then choose from the menu Help > Create Diagnostics Report. The corresponding zip file please post here. Thank you

Here is the diagnostics report:
Dorico (1.0 MB)

Hm, strange, from the logs it looks okay, so I would expect sound to come out.
What if you try a different audio driver? Can you please download the free driver FlexASIO from here?
After installation and restart of Dorico it shall appear in the list of drivers in the Device Setup dialog.
