World of Warcraft - WotLK "OpenVR: failed to locate module & DXVK Error"

You can’t use Vulkan on your iGPU. It’s too old (2010). Vulkan is only supported on Ivy Bridge (2012) and forward.

And it looks like you don’t have a dGPU, only an iGPU.

You can try to run the game without DXVK, which will translate the game to OpenGL
