When I open Ryzen master I'm presented with this opaque error message:
AMD Ryzen Master
Ryzen Master can only run with Virtualization Based Security (VBS) disabled in the Windows operating system. Please disable VBS and re-start Ryzen Master.
Virtualization-Based Security (VBS)!
OK
I've tried the following to resolve this without success:
1) Disable VBS in the Device Guard Group Policy (GPEdit)
2) bcdedit /set hypervisorlaunchtype off (in an administrative control panel)
3) uninstalling Hyper-V
Update since the original message was posted:
Disable the following Windows components:
Windows Hypervisor Platform
Virtual Machine Platform
Microsoft Defender Application Guard
Turn off this setting:
PC Settings > Windows Update > Windows Security > Device Security > Core Isolation > Memory Integrity (alternatively use the Search Function and search for Core Isolation). Ensure it remains off after a reboot.

You just need to go to device security and go to core isolation and turn off the memory integrity feature that uses vbs to prevent attacks inserting code into processes.
Solved, I had to disable "SVM" in the UEFI/BIOS. That error message from AMD was extremely misleading!

I went into my bios and SVM was already disabled by default. This didn't fix it for me. Any other options?

Nope, the error message is accurate.
If you check the document of VBS: https://learn.microsoft.com/en-us/windows-hardware/design/device-experiences/oem-vbs , you will know that it's a feature using hardware virtualisation to enhance system security. Thus if you disabled virtualisation support in BIOS, the VBS is naturally disabled. If you only play game and not use any kind of virtual machine, your method is good.
I have a friend who also experiencing the same issue, but he heavily use VMs, so SVM can not be disabled, and the other issue is VBS will be automatically enabled after reboot, so far he hasn't found any solution.

Ask your friend to take a look at this reddit comment.
I also need Virtualization, I use VMs too. This method worked for me

I've done all of the suggested operations
I also performed the bcdedit /set hypervisorlaunchtype off (in an administrative control panel)
I did not uninstall HyperV
SVM is disabled.
So far nothing has allowed me to launch ryzenmaster without getting the VBS error (outside of being able to launch when the computer was new).
any other suggestions that work?
[Edit - Microsoft Defender Application Guard is now off and still no joy]
Try this:
PC Settings > Windows Update > Windows Security > Device Security > Core Isolation > Memory Integrity (turn it off).
Make sure it stays off after the reboot.

I've disabled SVM in the UEFI/BIOS which did not resolve my issue.
I've also tried disabling VBS in the Device Guard Group Policy (GPEdit) which seems to only be a temporary fix. After a day or so of regular use and a couple reboots the system appears to restore itself and I'm right back to where I started with the same error message:
Ryzen Master can only run with Virtualization Based Security (VBS) disabled in the Windows operating system. Please disable VBS and re-start Ryzen Master. Virtualization-Based Security (BVS)!
As an update, it turns out there are multiple System Components that utilize VBS (I mistakenly assumed only Hyper-V did) and they must all be uninstalled via Programs & Features > Turn Windows Features On or Off.
For example,
Windows Hypervisor Platform
Virtual Machine Platform
Microsoft Defender Application Guard
If you disable those in addition to Hyper-V than Ryzen Master should work even with SVM enabled in the UEFI. Report back if disabling those additional components worked for you.
That's wrong. Intel VT / AMD-V / SVM / Hyper-V / Windows Hypervisor Platform / Virtual Machine Platform is Virtualization. Virtualization Based Security USES (as the name suggests) Virtualization, not the other way around. Naturally, if you disable virtualization, VBS will be disabled too, since it doesn't work without.
Though, it's not like VBS is the only thing that uses Virtualization. Many other things depend on it, and these things tend to be commonly used by software developers, like Android Studio (for developing android apps), Windows Subsystem for Linux, etc
Your "solution" of disabling virtualization to disable VBS is like removing your system disk because you want to delete a single file on it.

Correct however VBS is not used unless there is software installed that uses it, hence the suggestion to remove the software that uses it. MarcP-6643's idea of disabling SVM is more drastic as it impacts more than just software that utilizes VBS (there are virtualization programs and Windows security systems that can utilize SVM but don't use VBS).
If you mean my original solution of disabling SVM, that was indeed a shortsighted solution.
I think you misunderstood my comment.

There is no software using VBS.
But there is software that VBS uses.
That software that VBS uses is Windows Hypervisor Platform, Virtual Machine Platform, Microsoft Defender Application Guard. So by deactivating those, you disable VBS since VBS can't run without it. The reason VBS is disabled after removing those features is NOT that these features use VBS, and now since they're disabled VBS is disabled too.
Ah okay, thank you.
