Installing breaks Vulkan on iGPU

[silikeite]

I am on Arch Linux where I installed the primus_vk and lib32-primus_vk packages.
Upon installation, pvkrun vkcube did not work, printing out the error that it could not find the discrete GPU, which I was able to fix by symlinking nvidia_icd.json to nv_vulkan_wrapper.json.

Upon doing this however, I am no longer able to launch Vulkan applications with the iGPU, with the error
[1] 8496 segmentation fault (core dumped) vkcube.
