install.sh and rpi-vk-driver.json

[solsticedhiver]

rpi-vk-driver.json has a harcoded username, assuming pi as current username.

install.sh could replace that with acutal curernt user name

If that does matter because I have no idea of the purpose of the file, but with a wrong path ....

that file's contents do matter, as they tell the Vulkan Loader where to find the driver.
You can just edit the json file with your username for now
