Happening the same here.

Was trying to troubleshoot here but not sure where to start.

I have tried removing the preset extra configs and sourceType but no success.

module.exports = function (api) { // eslint-disable-line func-names
  api.cache(true);

  const presets = [
    ['@babel/preset-env', {
      targets: {
        browsers: ['last 2 versions']
      },
      useBuiltIns: 'usage',
      corejs: '3.0.0'
    }],
    '@babel/react'
  ];

  const plugins = [
    '@babel/plugin-syntax-dynamic-import',
    '@babel/plugin-proposal-class-properties',
    '@babel/plugin-proposal-do-expressions',
    '@babel/plugin-proposal-export-default-from',
    '@babel/plugin-transform-runtime'
  ];

  return {
    presets,
    plugins,
    sourceType: 'module'
  };
};

Just an update: I have a fix for this in babel-preset-modernize that should be released soon.

In the meantime, you can disable automatic modernization by passing new OptimizePlugin({ modernize: false }).

@developit, do you have a link to the PR with this fix? Thanks!
