But dxvk requires pretty new hardware that can run recent vulkan implementations.. The internet claims your card can, but its certainly failing to start vulkan
Heroic should be able to detect supported version now and install supported DXVK if Vulkan 1.2 is supported it will install dxvk 1.10 if vulkan 1.3 it will use dxvk 2.0 similar feature is coming soon for vkd3d
