I just tested the URL and the skip/bypass rule above is not working. Try one of these instead.
Adding an additional .* to the end of the existing skip/bypass rule.
# Enfold Theme font skip/bypass rule RewriteCond %{REQUEST_URI} ^/wp-content/themes/enfold/config-templatebuilder/avia-template-builder/assets/fonts/.*\.(eot|woff|ttf|svg).* [NC] RewriteRule . - [S=13]
Or a skip/bypass rule for the entire /config-templatebuilder/ theme folder
# Enfold Theme font skip/bypass rule RewriteCond %{REQUEST_URI} ^/wp-content/themes/enfold/config-templatebuilder/ [NC] RewriteRule . - [S=13]
