At least for me, the problem shows up simply with vulkan-tools installed (or using "guix shell vulkan-tools") using a guix commit after the latest (1.3.280) vulkan updates. Simply running "vulkaninfo" results in the error:

ERROR at /tmp/guix-build-vulkan-tools-1.3.280.0.drv-0/source/vulkaninfo/./vulkaninfo.h:412: Failed to initialize: Vulkan loader is not installed, not found, or failed to load.

A bit of local testing just now suggests setting LD_LIBRARY_PATH to the vulkan-loader package's lib dir should be enough to resolve the error.
