I'm also getting the same error when I run either desktop-with-xr-resolution or xr.

When I run desktop it doesn't crash but I'm getting a lot of errors from Vulcan:

I also tried removing "XR_APILAYER_LUNARG_core_validation" from the list in xr.rs line 80 but that resulted in failure to create the Vulcan instance without much more information on why:

Hi! I'm facing the same issue, did you manage to workaround/fix this?

I'm using a Quest2 and executing the application through Oculus Link.

[BleyChimera]

I am also getting the exact same errors as the ones in the opening issue.
SteamVR doesn't startup and it doesn't seem to interact with the program even if started up.

I think we simply don't have some dll needed to use this version of OpenXR?
Or maybe is some path somewhere that is broken?
