Module parse failed: unexpected token

[utopictown]

i got this when run yarn start, what configuration that i need to implement?

./node_modules/react-helmet-async/lib/index.esm.js 374:12
Module parse failed: Unexpected token (374:12)
File was processed with these loaders:
 * ./node_modules/babel-loader/lib/index.js
You may need an additional loader to handle the result of these loaders.
| var isDocument = !!(typeof window !== "undefined" && window.document && window.document.createElement);
| var HelmetData = class {
>   instances = [];
|   canUseDOM = isDocument;
|   context;

this is some of my packages that might be useful to debug

"react": "^18.2.0",
"react-dom": "^18.2.0",
"react-helmet-async": "^2.0.4",
"@babel/preset-env": "^7.1.0",
"@types/recordrtc": "^5.6.11",

"babel-plugin-object-to-json-parse": "0.0.7",

I got the same error with

    "react-helmet-async": "^2.0.4",,
    "react": "^17.0.2",
    "react-dom": "^17.0.2",

I tried to downgrade and the first version that works is :

"react-helmet-async": "^1.3.0"

is not a perfect but for now is the better solution I found
