[ERROR] Could not create openxr system: XR_ERROR_FORM_FACTOR_UNAVAILABLE about uevr HOT 3 CLOSED

Exactly the same thing happens to me, no matter which game I try to start.
Would be really nice to get some advice here :)

from uevr.

I was facing the same error message for my setup. I managed to get it running, so maybe a similar approach can be helpful for different setups as well.

OS: windows 10
Graphics card: NVIDIA GeForce RTX 3080ti
CPU: Intel i7 11700k
Headset Model: meta quest 3
Streamer: Quest Link (cable)
PC: Oculus App

Solution:
After I set Oculus as the active openXR Runtime the issue disappeared.
(Oculus App in Windows > Settings > General > "Open XR Runtime" click on "set Oculus as active"

from uevr.

I managed to get the game running in VR mode in the following setup by checking / resetting the settings in the following applications:

on PC:
1.Start Steam app and within Steam launch SteamVR. Check Settings-->OpenXR. The current OpenXR Runtime was for whatever reason empty in my case. I changed / selected that in SteamVR

2.Start Oculus app. Check in Setting-->General the OpenXR Runtime. The text after 'Current OpenXR Runtime: ' was blank, for whatever reason no VR runtime was filled in. I changed/selected SteamVR. I clicked on Set Oculus as active but that didn't work. When going back to SteamVR app and in settings OpenXR I selected SteamVR again and that value was 'suddenly' displayed in Oculus app. However I don't start/use the Oculus app when running the game. I use Steam app and virtual desktop streamer app only.

3. Start Virtual Desktop Streamer app. Go to Options. I selected the following values

4. I closed all above apps and started on my PC only Steam app (and not launching Steam VR), Virtual Desktop Streamer and the UEVR app. After this I continued in Quest 3 device

on Quest3

1. Start Virtual Desktop and connect to PC wireless
2. using Quest 3 (seeing my desktop/PC) I launched HogwartsLegacy in Steam
3. using Quest 3 (seeing my desktop/PC) I injected the openXR settings using Synced Sequential as VR_RenderingMethod in the UEVR app
   

and voila the game runs in VR.
