this is the replacement of that public function and worked fine for me:

public function remove_custom_font_google_url( $fonts ) {
    $custom_fonts = Bsf_Custom_Fonts_Taxonomy::get_fonts();
    if ( ! empty( $custom_fonts ) ) {
        foreach ( $custom_fonts as $key => $value ) {
            $font_key = "'" . $key . "'";
            if ( isset( $value['font_fallback'] ) && $value['font_fallback'] ) {
                $font_key .= ', ' . $value['font_fallback'];
            }
            if ( array_key_exists( $font_key, $fonts ) ) {
                unset( $fonts[ $font_key ] );
            }
        }
    }
    return $fonts;
}
