lost halion drum set sound after switching audio interface

my project (marimba, vibraphone, drum set) was working fine with my macbook pro built-in audio interface.
When I switched to my external audio interface (Apogee Duet), I lost the drum set sound while the marimba and vibraphone still work fine.
Switching back to the built-in interface does not help, nor “load sounds for unassigned instruments”, “reset playback overrides”, and creating a new drum set.

I am using the Halion Sonic SE 3 with the default [GM 129] Stereo GM Kit and Dorico 2.2. When clicking on the keyboard in the Halion window, I hear drum sounds sounds.
Any idea on how to get my drum set back?

Doing Play > Playback Template and choosing ‘HSSE+HSO (Pro)’ and clicking OK doesn’t sort it out?

If not, can you please zip up and attach the project here?

that worked! thanks so much for all your help (especially on a Sunday!)
