Could incompatible Node.js or npm versions lead to this specific error, and how do I verify compatibility?

Yes, incompatible Node.js or npm versions can certainly cause problems, including the 'cannot find module' error, if `react-scripts` (or its underlying dependencies) has specific version requirements. To verify compatibility: 1. **Check your Node.js version:** Run `node -v` in your terminal. 2. **Check your npm version:** Run `npm -v` in your terminal. 3. **Consult documentation:** Refer to the Create React App documentation or the `react-scripts` package page on npmjs.com to see the recommended Node.js and npm versions. If your versions are significantly different, consider using a Node Version Manager (`nvm` for Linux/macOS, `nvm-windows` for Windows) to switch to a compatible Node.js environment.
