B550-I Ryzen 5800X: DtsApo4Service.exe crashes (Sonic Studio 3 effects not working)

[fatalhalt]

Hello guys,

I have a following new build:

AMD Ryzen 7 5800X
ROG Strix B550-I Gaming
Windows 10 20H2 (19042.630)

I have been fighting with trying to get Sonic Studio 3 effects working and the experience so far has been unbearable and painful.

- the audio doesn't work unless I check "Disable All Sound Effects" in Realtek Audio Console, but when I do this then I can't use Sonic Studio 3 effects...
- I have tried clean reinstalling Asus audio drivers without any luck, still can't get Sonic Studio 3 effects working
- I have tried clean installing MoKiChU's AUDIO_Realtek_UAD_ASUS_ROG_SS3-DTS_MB_v6.0.9047.1.7z which at least made my sound continue working without needing to "Disable All Sound Effects", but any changes made to EQ/effects in Sonic Studio 3 are taking any effect. While MoKiChU driver pack worked for a moment , soon I have been back to square one with sound not working again unless I check "Disable All Sound Effects"

I'm trying to understand if my problems are related to DTS APO4x not being fully functional (the DtsApo4Service.exe is unable to start). I know that Sonic Studio 3 depends on Nahimic service/driver, but is that true with DTS APO4x?

DtsApo4Service.exe crashes whenever Windows 10 starts, or whenever I try to manually start it:

Faulting application name: DtsApo4Service.exe, version: 1.3.3.0, time stamp: 0x5e4f3765
Faulting module name: dtscnt64.dll, version: 4.2.7.0, time stamp: 0x5ea9603d

or

The DtsApo4Service service terminated unexpectedly.

I have tried to manually start:
> cd C:\Windows\System32\DTS\PC\APO4x\
> DtsApo4Service.exe -console
it crashed and prints:
CPUBITS 0x3ff
AVX HIT

C:\Windows\System32\DTS\PC\APO4x>DtsApo4Service.exe -console
4: Running in console mode. Press enter to start.

4: Starting Rpc Server..
4: DtsApoService in OnStart
4: Press enter to stop the server and exit.



CPUBITS  0x3ff


AVX HIT

Has anyone experienced crashing DtsApo4Service.exe? Could this be related to AVX instruction on Ryzen 7 5800X?

I'm on not Ryzen but a 10900k with the Asus Maximus XII Hero /Wifi and have started having this error pop up as of today, which is 2 days after a complete clean install without this error. I've tried completely reinstalling the realtek drivers, uninstalling and even disabling it bios after removing the drivers and I'm still getting this error.
