'npm error code 128' keeps appearing even after verifying Git installation and network. What else could be the problem?

If Git and network seem fine, consider issues with the local Git environment or npm cache. Your local Git repository might be corrupted (e.g., in `node_modules` if a package has a `.git` folder). Try clearing the npm cache with `npm cache clean --force`. You might also delete the `node_modules` directory and `package-lock.json` file, then run `npm install` again. Ensure there are no lingering Git processes or permissions issues in your project directory that might prevent Git from operating correctly. Sometimes, updating Git to its latest stable version can resolve subtle bugs.
