Is it just me, or did it actually do a double take? Not often you see an exclamation mark in an error prompt.
There is a long thread open in Drivers Forum concerning Ryzen Master and Hyper-V.
Ryzen Master version 1.3.xx and up doesn't work or run with Hyper-V installed (VBS). https://community.amd.com/message/2859010?q=ryzen%20master
Seems like AMD finally made it official by putting a warning now with Ryzen Master that it doesn't work with Hyper-V activated.
I do not have Hyper-V enabled, it is not even installed, nor is VBS enabled. It is explicitly disabled, and I still get this message.
I have this same issues with VBS disabled, you ever get it figured out?
Windows version 1909 has a new feature called "Sandbox" which uses VBS the same as Hyper-V.
See if Sandbox is enabled.
