OMEN Audio Control crashes

[Chonio]

I have a problem with OMEN Audio Control - whenever I try to open the "Output" tab, the application just shuts off without any error message or whatever. 
It started to malfunction today, after I tried to turn off the "Bang & Olufsen Experience" switch - when I clicked that, the application shut off and from that moment I cannot access the "Output" tab.
There were no issues in the past but yesterday the Windows Update installed the "Realtek semiconductor" update, so I assume it has to do something with that. Unfortunately, I cannot uninstall this update.

HP Support Assistant, Device Manager and Windows Update do not detect any updates.

Is there any way to fix it?

Please help, I am desperate...

Please perform a clean install Audio software/driver, this should help.

   (a) Download the following driver and save on your computer,
                     https://ftp.hp.com/pub/softpaq/sp107001-107500/sp107247.exe

   (b) Go to Device Manager, Sound to uninstall sound driver (Realtek) and reboot,
   (c) Right click downloaded file and select Run as administrator,
  (d) Reboot again.

Regards.

It worked only partially, now I can access the Output tab, but the "Bang & Olufsen Experience" switch disappeared 😞
While installing the driver, the system asked me if I want to install the older version of OMEN Audio Control, so I assume this version does not have this switch, but how do I install the version that has it? 
Or maybe something else is the issue?
