Build hangs on angular 17 webpack completion in GitHub Actions

Please do correct the title if deemed unsuitable, I'm not that well-versed in front-end development 🥲

📣 Feedback / 🐛 Bugs

As the title suggests, when the build completes, it does not run to completion. Rather it hangs until github times it out (which previously was 6 hours but I hard-limit it to 30 minutes now).

Weirdly enough though, it runs fine locally but in GitHub Actions it fails. Also if I do debug: true in codecovWebpackPlugin configs, it hangs locally too.

Sample run: https://github.com/kwongtn/rosak_firebase/actions/runs/9605749364/job/26493953821

When I disable codecovWebpackPlugin , it builds nicely, therefore isolating the issue:

My repo & branch: https://github.com/kwongtn/rosak_firebase/tree/staging

Help? 🥲

Start with the linked GitHub Actions run and the repository's staging branch, comparing the hanging build with the run where codecovWebpackPlugin is disabled. Inspect the codecovWebpackPlugin configuration, including debug mode, and reproduce the build in GitHub Actions. Done means the Angular 17 webpack build completes with the plugin enabled without timing out.
