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:

Help? 🥲
