Humm I know .23 just dropped when might this patch make it into the main line?

Unfortunately it probably won't. This issue happens because the openXR initialization that Metro Awakening does is off-specs, and WiVRn developers aren't very willing to get lax on checks to make it work: WiVRn/WiVRn#232

If you see on the bug report, I've even opened a bug report at PLAION (the publisher) https://playersupport.plaion.com/hc/en-us/requests/150094 but what happens on it is not open to the public. The best hope we have is that they fix it in Metro Awakening itself and a future patch allow WiVRn to run it without my pach.

Sigh so basically shit out of luck unless I want to go figure out envision and the many other complex moving parts or deal with crappy ALVR performance. Argh, thanks for clarifying.
