HP G2  SU4 Beta (1.6.13.0) Win11 23H2  SteamVR or WMR or OASIS VR driver

The HP G2 goggles work very well in 2020 and have been using them for several years.

In 2024 when I CTRL+Tab I hear the chime indicating I've switched to VR, the desktop screen goes black, sound comes from the G2 speakers, and I all see in the G2 is a soft uniform gray screen.  The desktop screen never shows the 3D - pair of screens I see in FS2020.

After a few seconds, the chime sounds again and the desktop screen again shows a 2D image.   But input is still directed to the VR screen. 

I need to use Win+Y to move back to the 2D screen on the desktop. 

The focus for the mouse changes from the desktop to the VR screen and must be moved back to the 2D screen using Win+Y.

What do I not understand about VR in the current Beta?

Also have no problems with VR in Assetto Corsa. 

two days later in FS2024 SU3 no beta- made the permanent move to Oasis VR driver for WMR devices.  VR in FS 2020 is spectacular at 40 FPS with great clarity and smoothness.  Assetto Corsa works perfectly.  The Steam VR tutorial works perfectly.

I am now at the point that trying to run FS2024, even in 2D mode, does not work IF I have loaded the Oasis driver and started Steam VR.   If I start FS2024 with no VR stuff loaded - I am standing outside the aircraft in 2' 45" with dozens of addons and detailed airports.

When I start VR Steam and then start FS2024 I am at the Main Menu in 2' 10".  I then select Free Flight with a default Asobo aircraft and airport and have an empty Community Folder.  The sim starts to load the scenery and makes it's first move to lower the visual altitude as if it were going to show the departure airport.  But, at that point the rotating arrow in the lower right corner slows down to one revolution every minute or so.  After 10-minutes the sim is still loading.   

The G2 goggles show me the VR home with a big black, blank desktop.  I can move around the room but cannot select anything because the desktop is solid black. 

While the sim is slowly loading it's CPU usage is less than 1% while the entire CPU usage s less than 10%.  The sim does no disk reads and very few network ops. 

However - three Steam VR processes are running:  VRcompositor, VRTour, and VRSteam.  They each are using about 3% of the CPU and doing very few IO ops.

I have deleted and reinstalled all the Steam components.  

How do I make VR work in FS2024 with HP Reverb G2 goggles?
