v62 breaks apps using the official Khronos OpenXR Loader

[koujaku]

StereoKit has been successfully using the official Khronos OpenXR Loader for around a year now, but v62 seems to break apps that use the Khronos loader. I've tried with OpenXR Loader v1.0.30 and 1.0.33, and both fail the same way. If I swap out to the OpenXR Loader included in the Oculus SDK, the same app does still work.

Here's the logs I get when trying to initialize OpenXR:

I have the same problem with Quest2 and Quest3 headsets,  v62...

Hey Meta guys, could you just confirm that you are aware about this problem?
Without fixing it, all your headsets are worthless crap at this moment, I hope you realize that.

[fewerwrong.x]

Khronos is working on a fix, but you can use my fork in the interim if you want, it has changes to load liboculus_forward loader from the VrDriver path: https://github.com/amwatson/OpenXR-SDK-Source 

[koujaku · Accepted solution]

Looks like OpenXR Loader v1.0.34 released today, and it fixes this issue for me!
