After a fresh git clone of my project, yarn install, the command yarn start fails with this error :

./node_modules/react-multistep/dist/index.js 273:97
Module parse failed: Unexpected token (273:97)
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.

>       }, showTitles && /* @__PURE__ */import_react.default.createElement("span", null, s2.title ?? i2 + 1));
|     } else if (stylesState[i2] === "doing") {
|       return /* @__PURE__ */import_react.default.createElement(Li, {

Could you help me to solve this error ?

After looking for similar errors, I found this solution but it did not work :

I made a workaround. I compared my old and new package-lock.json of my projects and I saw some @babel lib version changed to v7.20.2 (on Nov 4th, 2022). I overwrote the new package-lock.json with old one and my react app built and ran successfully again. I then changed (downgrade) some of @babel package in my package.json and it is solved the problem. Put this lines into your package.json file:

"@babel/core": "7.19.6",
"@babel/generator": "7.19.6",
"@babel/compat-data": "7.19.4",
"@babel/helper-compilation-targets": "7.19.3",
"@babel/helper-create-class-features-plugin":"7.19.0",
"@babel/helper-module-transforms":"7.19.6",
