Note that the development build is not optimized. To create a production build, use npm run build.

[UtmostCreator]

you are forget to export an component

Yeah, I have exactly this problem. in babel.config.js file, but in your case it could be any other file.
Before:

// ./babel.config.js
module.exports = {
  presets: ["@vue/cli-plugin-babel/preset"],
};

After:

// ./babel.config.js
export default module.exports = {
  presets: ["@vue/cli-plugin-babel/preset"],
};

However, if I resetar the client, then I have the following error:

 ERROR  SyntaxError: DISK:\path\to\my\project\client\babel.config.js: Error while loading config - Unexpected token 'export'
DISK:\path\to\my\project\client\babel.config.js:1
export default module.exports = {
^^^^^^
