Why does a bunch of errors fall out when starting even a default Vue3 application?

Question

Vue.js

Here is the structure:

On the Stack, it is recommended to slightly tweak devServer and webpack.config.js, but I don’t see this at all in the default application.
My assumption is that the error occurs because I'm behind a corporate proxy. But I added a proxy to Node itself, and there are no more problems with it.
