I can confirm it is now working as expected after upgrading to 2.9.5. Thank you guys for your effort.

try this, force him to use esm bunder.

export default defineConfig(({ command }) => {
  return {
    resolve: {
      alias: [
        {
          find: "@vue/runtime-core",
          replacement: "@vue/runtime-core/dist/runtime-core.esm-bundler.js",
        },
      ],
    },
  };
});

The reason for this is because if your project import a package thats is export by cjs, for some reason, the vue-core runtime will also import cjs, that’s why we got an error here, btw this also causes the hmr not works in vue file.
