Tried a previous commit of OpenXR-SDK-Source (https://github.com/KhronosGroup/OpenXR-SDK-Source/tree/033c76dd7561730de3aee3ef623e9e5be6f551df), works fine. Probably something has broken in the 1.0.27 update?

Aww crap, happens every time I forget to test openxr-hpp with a new release 🤦 . I don't see what object it's trying to make - I'll take a look later. Presumably somebody added a vendor extension with a weird type in it that the wrapper doesn't know how to default-init.

The issue is that XR_FB_spatial_entity added XrAsyncRequestIdFB but didn't define a XR_NULL_ASYNC... constant to go with it, so it's considered non-defaultable and therefore crashes the generator. I managed to fix it by having atom types default to "0" instead of returning None.

This appears to be working fine now with the above fix (plus more fixes).
