Has anyone encountered something like this?

Background: About a week ago, the (React) project was working fine and everything was normal.

Around the same time, I started working on a new project, but this time using React Native. Both projects are on the same working machine but naturally in different folders. During the initial setup of the React Native project, I had to deal with a bunch of errors, and apparently, in one of those error resolutions, I either updated a package (probably unnecessarily) or installed a new one.

I returned to the old project only a couple of days later and found this error. Therefore, I can't determine what exactly broke it.

I tried npm clean cache + delete node_modules + delete package-lock.json, but it didn't help.

Rolling back to an old commit also didn't resolve the issues (even going back 5 commits).

The project was originally built using CRA (Create React App). There are no files such as .babelrc, babel.config.js, webpack.config.js.

Failed to compile.

./node_modules/ml-matrix/src/symmetricMatrix.js 7:2
Module parse failed: Unexpected character '#' (7:2)
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.
| export class SymmetricMatrix extends AbstractMatrix {
|   /** @type {Matrix} */
>   #matrix;
|   get size() {
|     return this.#matrix.size;

Tryed to use @babel/preset-env, but its doesnt work Remove node-modules + package-lock.json + npm clean cache - doesnt work Also i tryed prev commit, same - just doesnt work

Hey, i think youre just not good at programming, if you cant deal with this little error by yourself. Just delete your gitHub and go work at the construction site or something
