Hello,
I was also having issues launching this program. My issue was that when I launched the program I would get:
[4.704s] [ext: omni.audio2face.player-0.1.1] startup
A s s e r t i o n f a i l e d !
P r o g r a m : C : \ U s e r s \ James \ A p p D a t a \ L o c a l \ o v \ p k g \ a u d i o 2 f a c e - 2 0 2 1 . 2 . 3 \ k i t \ k i t . e x e

E x p r e s s i o n : F A L S E

However, I was able to fix it by replacing the files:
C:\Users\%USERNAME%\AppData\Local\ov\pkg\audio2face-2021.2.3\exts\omni.audio2face.core_deps\deps\py\_sounddevice_data\portaudio-binaries\libportaudio64bit.dll
and
C:\Users\%USERNAME%\AppData\Local\ov\pkg\audio2face-2021.2.3\exts\omni.audio2face.player_deps\deps\py\_sounddevice_data\portaudio-binaries\libportaudio64bit.dll
With the file portaudio-r1891-build.zip\portaudio-r1891-build\lib\x64\Release\portaudio_x64.dll (Rename this file to “libportaudio64bit.dll”) in this zip file: https://github.com/adfernandes/precompiled-portaudio-windows/blob/master/portaudio-r1891-build.zip?raw=true
I figured I’d post this in case it helped anyone here
