That "WebGPU: Disabled" can be anything from "Chrome considers the driver too buggy to enable WebGPU on by default for users" to "Chrome doesn't support that GPU/OS/Driver combo for WebGPU at all". You can try force enabling some various GPU flags in chrome://flags/ but whether that's successful will depend on the particular setup.
Until that switches from "Disabled", no WebGPU content or demos will load in your Chrome instance.
You can see overall user support https://web3dsurvey.com/webgpu. Particularly Safari on iOS/macOS and most browsers on Linux are still yet to start rolling out support by default.
