I create a sample project for you - https://github.com/Djaler/obsolete-webpack-plugin-vue-cli-modern-mode-bug-sample

Steps to reproduce:

npm install
npm run build
Run project using any HTTP-serve. For example, serve.

npm install -g serve
serve -s dist

Open in modern browser (latest Chrome, for example)
You will see error in console

This happens because in modern mode vue cli produces two versions for each script - for modern and legacy browsers. Modern browser will load <script type=module>: <script type=module src=/js/obsolete.5561cfbb.js></script> and will not load <script nomodule: <script src=/js/obsolete-legacy.5561cfbb.js nomodule></script>. And legacy browser will do the opposite.

The problem is that your script is not designed to run as an ES-module.
