We don't use Object.assign in Vue codebase precisely to support IE. This is likely to be a configuration issue of some sort.

Maybe you wanted to create an issue on the vuejs/vue-cli repository. If you do, please provide a boiled down reproduction with no extra dependencies (no vuetify)

@posva Please take a look at the linked vuetify issue. There I've been told to create a ticket here because the object.assign polyfill seems to be there some time ago but now it stops working.

Adjust your .browserslistrc to include ie11. Vue-CLI updated the default by adding not dead which now excludes IE, a "dead" browser.

@sirlancelot Thanks for the advice. But even after removing the "not dead" part from the browserslist at package.json I'm still getting the same error at the simple vue project.
Just calling
console.log(Object.assign({}));
at main.js (without added vuetify).

npx browserslist
is listing IE11 and even IE10.
