This means that your graphics card doesn't support the Vulkan backend, which is the main graphics API that pretty much all Godot 4 games use, including this one. The command is telling you to run it using OpenGL 3, but doing that results in an unplayable mess (I did it on my PC because I had the same problem and you can't see anything). You could try updating your drivers, and if that doesn't work, you'd have to get a new graphics card.
