Resolve Webpack Build Errors on Mac in VSCode

I need someone who is a VERY familiar with MacOS for one-time remote assistance with fixing a webpack build issue that occurs on a Mac in VSCode. The build runs on an old version of Node v12.22.7. The build is failing with errors during the initial build phase, although it runs fine on a PC. There have been no recent changes to the code or configuration that might have caused this issue - we are trying to get it to run on a new computer where it hasn't run before. My goal is to resolve the issue without changing the existing build. I'm pretty sure it's just a version issue with what's installed on the Mac in question.

Key Requirements:
- Diagnose and resolve the build errors occurring on a Mac.
- Ensure the build runs successfully on Node v12.22.7.
- Maintain compatibility with existing PC build setup.

Ideal Skills and Experience:
- Strong experience with webpack and Node.js
- Familiarity with cross-platform build issues, particularly between Mac and PC
- Familiarity with VS Code
- Ability to troubleshoot and resolve build errors efficiently
- Experience with maintaining consistent build environments across different operating systems
- Experience with SFCC/SFRA is a plus
