regenerator.mark is not a function svelte + rollup + babel - babeljs

Question

I am getting the error Uncaught TypeError: regenerator.mark is not a function
I checked bundle generated regenerator is { __esModule: true }
seems #babel/plugin-transform-runtime, it's not able to inject runtime.js in a bundle.
here's Rollup config:-
export default {
input: 'src/main.js',
output: {
sourcemap: true,
format: 'iife',
name: 'app',
file: `public/build/${bundleName}`,
},
plugins: [
svelte({
compilerOptions: {
// enable run-time checks when not in production
dev: !production,
},
preprocess: preprocess(),
}),
babel({
extensions: ['.js', '.mjs', '.html', '.svelte'],
runtimeHelpers: true,
exclude: 'node_modules/core-js/**',
presets: [
[
'#babel/preset-env',
{
// debug: true,
useBuiltIns: 'entry',
corejs: '3',
targets: {
browsers: ['safari >= 5', 'ie >= 11', 'not dead'],
},
},
],
],
plugins: [
'#babel/plugin-syntax-dynamic-import',
[
'#babel/plugin-transform-runtime',
{
useESModules: false,
},
],
],
}),
resolve({
browser: true,
dedupe: ['svelte'],
}),
commonjs(),
includePaths(includePathOptions),
production && terser(),
production && gzipPlugin(),
],
};
