After installing font awesome free pack, i had the following message:

+ @fortawesome/free-solid-svg-icons@5.9.0
added 258 packages from 131 contributors, removed 234 packages, updated 1532 packages and audited 27419 packages in 120.094s
found 52 vulnerabilities (25 low, 10 moderate, 17 high)
run `npm audit fix` to fix them, or `npm audit` for details

then i run

npm audit fix

and i got:

npm WARN stylelint-webpack-plugin@0.10.5 requires a peer of webpack@^1.13.2 || ^2.7.0 || ^3.11.0 || ^4.4.0 but none is installed. You must install peer dependencies yourself.

npm WARN terser-webpack-plugin@1.3.0 requires a peer of webpack@^4.0.0 but none is installed. You must install peer dependencies yourself.

+ imagemin-webpack-plugin@2.4.2

+ browser-sync@2.26.7

+ copy-globs-webpack-plugin@0.3.0

now running yarn like this:

yarn start

gives
