Ah I found a workaround for anyone else int he smae situation. Add these lines to your custom.css file:
/deleteme when helix ultimate is fixed/
.fa { font-family: var(--fa-style-family,"Font Awesome 6 Free")!important; font-weight: var(--fa-style,900); }
.fa-brands, .fab { font-family: "Font Awesome 6 Brands" !important; }
.fa-classic, .fa-regular, .fa-solid, .far, .fas { font-family: "Font Awesome 6 Free" !important; }
.offcanvas-menu .offcanvas-inner ul.menu > li.menu-parent > a > .menu-toggler::after,
body.ltr .sp-megamenu-parent > li.sp-has-child > a::after,
body.ltr .sp-megamenu-parent > li.sp-has-child > span::after,
body.ltr .sp-megamenu-parent .sp-dropdown .sp-dropdown-items .sp-has-child > a::after
{font-family: "Font Awesome 6 Free"; }
