And installing version of favicon prior to 7.0 (like 6.2.2 for now) is installed deprecated dependencies.

see the typescript boilerplate for reference :

If you're trying to run npm run dev with this boilerplate project, you get the following exception:

webpack 5.74.0 compiled with 1 error in 9124 ms

The fix for this is to change babel version, fix webpack.config.js etc. I am going to provide a pull request in a few minutes.
