./node_modules/pako/lib/zlib/trees.js Module parse failed

Started seeing this all of a sudden today for ReactJS builds using babel-loader. Not sure if this was a babel change that caused or if this is something on pako end.

I think line 278 in trees.js, this:

// tree_desc *desc; /* the tree descriptor */

Just needs to go to:
// tree_desc *desc; the tree descriptor

Update: A couple people have already opened PRs to fix this.

Yep, until they doesn't solve this issue, you can fix on your machine by removing all comments inside node_modules\pako\lib\zlib\trees.js and after this you can restart app

I upgraded some babel packages as mentioned here: https://stackoverflow.com/questions/74323826/module-parse-failed-unexpected-token-257106-you-may-need-an-appropriate-load but it looks like @puzrin has committed changes to fix the original problem. Closing issue. Thank you @puzrin.
