FontAwsome problem

Hi,
I.m using WP 5.7, PHP 7.4.
Official Plugin Font Awesome is installed (latest version). No conflicts.
Font Awesome icons are not showing on front (any vresion)
I’m getting
<span class=”dashicons undefined fa-undefined after-menu-image-icons”></span>
instead <i fa.. whatever
No errors in console…

Please assist. Probably PRO version will solve that?
