Activities of "Raef_khallad"

Dears, i've followed the getting started guide to start up my first downloaded solution. i got an error stating that file: 'http://localhost:4200/assets/metronic/themes/default/css/style.bundle.min.css' is not found (the screenshot below):

i've tried removing and reinstalling my Node_modules using NPM and Yarn with no luck to fix this issue.

any suggestions please?
