Steam Proton all games crashing on EndeavourOS due to Vulkan library package choice

gistfile1.txt

When installing AMD drivers on EndeavourOS I was prompted to choose Vulkan packages. I chose `amdvlk lib32-amdvlk` which turns out to have been a mistake. This led to almost every game using Proton crashing on launch with one of the following two error messages in the logs (among much longer more unique stack traces). The "correct" packages which resolved this issue are `vulkan-radeon lib32-vulkan-radeon`.

Error type 1, from games including Craft the World, Ring of Pain, Slipways:
