IE11 Error: SCRIPT1006 - Expected ')' with vue app - vue.js

Question

I am having difficulties telling vue to polyfill my application in a way that it runs on IE11.
If I understand everything correctly, I have to tell my npm build to insert core-js and regenerator-runtime for my generator functions.
The app works fine on Chrome/Firefox, but I persistently get the error SCRIPT1006: Expected ')' on IE11.
Can someone point me in a direction to solve this?
My package.json looks like this:
{
"name": "vue-form",
"version": "0.1.0",
"private": true,
"scripts": {
"serve": "vue-cli-service serve",
"build": "vue-cli-service build",
"lint": "vue-cli-service lint"
},
"dependencies": {
"babel-polyfill": "^6.26.0",
"bootstrap": "^4.5.3",
"core-js": "^3.6.5",
"vue": "^3.0.0",
"vuetify": "^2.4.2"
},

"#vue/cli-service": "~4.5.0",
"#vue/compiler-sfc": "^3.0.0",
"babel-eslint": "^10.1.0",
"eslint": "^6.7.2",
"eslint-plugin-vue": "^7.0.0-0"
},
"eslintConfig": {
"root": true,
"env": {
"node": true
},
"extends": [

"eslint:recommended"
],
"parserOptions": {
"parser": "babel-eslint"
},
"rules": {}
},
"browserslist": [
"last 1 version",
"> 1%",
"IE 10"
]
}
my babel.config.js:
module.exports = {
presets: [
['#babel/preset-env', {
"useBuiltIns": "entry"
}]
],
plugins: ['#babel/plugin-transform-parameters', '#babel/plugin-syntax-dynamic-import']
}
and my vue.config.js:
module.exports = {
// options ...
publicPath: './',
transpileDependencies: ['bootstrap', 'vuetify']
}
Does anybody have any clue on how to fix this?
Cheers
