Description

I'm not quite sure how to structure this issue, so here it goes.

I created a Vue 3 project with webpack and typescript, then modified the `vue.config.js` file and tested some options. **I'm not sure if there is a function name or a file I'm expected to exclude somehow.**

Seed is 0, most of the time I get console errors, sometimes it works in different ways.
```
const WebpackObfuscator = require('webpack-obfuscator');
module.exports = {
transpileDependencies: true,
configureWebpack: {
plugins: [
new WebpackObfuscator({
compact: true,
rotateStringArray: true
})
]

}
};
```

Seed 9055:

Seed 221155
Page empty: Console error:
`Uncaught DOMException: Document.querySelector: 'style[data-vue-ssr-id~=\x22449b31f0:0\x22]' is not a valid selector`

With more options:

```
new WebpackObfuscator({
compact: true,
identifierNamesGenerator: 'mangled-shuffled',
rotateStringArray: true,
seed: 0,
selfDefending: true,
shuffleStringArray: true,
simplify: true,
stringArray: true,
stringArrayIndexesType: [
'hexadecimal-number'
],
stringArrayEncoding: ['base64'],
stringArrayIndexShift: true,
stringArrayWrappersCount: 1,
stringArrayWrappersChainedCalls: true,
stringArrayWrappersParametersMaxCount: 2,
stringArrayWrappersType: 'variable',
stringArrayThreshold: 0.75,
target: 'browser',
})
```

Console error `Uncaught TypeError: can't access property "charAt", G is undefined`

Am I missing something I should be doing ? Or is it an issue with webpack-obfuscator?

Research direction

Start with the reported Vue 3 project configuration in vue.config.js and reproduce the console failures using the shown webpack-obfuscator options and seeds. Compare the selector error and the charAt error across configurations, then review the discussion or findings in related issue #123. Done means identifying a reproducible incompatibility or a specific exclusion/configuration that prevents the failures.
