How can I restore DELETED WMR 3 virtual desktops?

Hi,

A while ago I accidentally deleted the 3 virtual display created automatically when starting WMR.

I guess I was following this procedure to delete them but I can't find a way to restore them .

I was not aware at the time that there is a setting option in WMR to do this or, later I found, the registry entry.

Now I am unable to open native applications in VR. They all open on the 'real' desktop.

I need to restore the 3 deleted displays to be able to play native application like Edge.

When I open the "Display Settings", while WMR is running, I only see the 2 connected monitors. I need to restore the ones I deleted.

I already did the following and it did not help:

Uninstall & Reinstall WMRReset WMR settings and environment settings
Disabled the option to "Create virtual displays for classic apps when mixed reality starts" & restarted my PC
Enabled the option to "Create virtual displays for classic apps when mixed reality starts" & restarted my PC
Made sure:[HKEY_CURRENT_USER\SOFTWARE\Microsoft\Windows\CurrentVersion\Holographic] "PreallocateVirtualMonitors"=dword:00000001
While my VR is connected and running, I clicked the "Detect" button and got a red message: Didn't detect another display.
I even tried to create my own virtual display using this how to remove display but while I was able to create a virtual display it is not related to WMR since the native app still open on the (real) desktop.
Tried to see if there are any monitors under device manager and there were none.

What else can I do? How can I restore those virtual displays?

I am running latest build for win10

VR is HP reverb Gen1

My GeForce 1080ti has it's latest driver

Games are running fine on the VR

Thanks
