Thanks for reporting!

I'm actually not sure about its cause since it should be the issue with sharp. https://github.com/lovell/sharp/issues/3589 might be related, so could you try setting the config below? It overrides the default chromaSubsampling value used by astro-better-image-service and uses the sharp's default settings.

import betterImageService from "astro-better-image-service";
import { defineConfig } from "astro/config";

export default defineConfig({
    integrations: [
        betterImageService({
            sharp: {
                avif: {
                    chromaSubsampling: undefined
                },
            },
        }),
    ],
});
