Vulkan Runtime Libraries (often abbreviated as VulkanRT) is a cross-platform 3D graphics and compute API. Think of it as a translator between software (like a video game) and hardware (your graphics card). Compared to older standards like OpenGL, Vulkan is designed for higher performance, giving developers more direct control over the GPU and distributing tasks more efficiently across multiple CPU cores. It's an industry standard comparable to Microsoft's DirectX 12, developed and maintained by the Khronos Group.

If you believe a specific application is causing issues, reinstalling your graphics driver is the best way to repair the Vulkan installation, rather than trying to uninstall it directly 1.2.1. Vulkan vs. DirectX vs. OpenGL
