The error is narrowed down to this line:

https://github.com/shader-slang/slangpy/blob/630de94b3fc0722627f00051eb2fd20e5c8c9a01/src/sgl/device/device.cpp#L179

It also seems that RHI failed to find any vulkan devices.

Checking out to commits before 2beb521 seems to fix the problem for me. I'm still looking into the issue.

Realized this is an issue caused by sgl not having bindless feature. Closing this issue as it should be solved by the bindless branch: https://github.com/shader-slang/slangpy/tree/bindless
