Vue.js - ERROR in Conflict: Multiple assets emit different content to the same filename index.html

if I create a new vue.js project on my macbook and compile it with "npm run serve", I get the following error.
I haven't changed any file since creating it.

markus@Markuss-MBP meinerstesprojekt % npm run serve

> meinerstesprojekt@0.1.0 serve
> vue-cli-service serve

Do you know why this doesn't work? Unfortunately, I couldn't find the solution by searching the web

When you hit vue create your-project-name Select ([Vue 3] babel,eslint) and try to npm run serve.

And also you can use vue ui to start a new project or import old one, and see everything about your project run in a GUI in your browser so you can figure out any problem.
