Sage 10 Gravity Forms Add Block not showing in frontend

sage

Hi,
when i try to add a gravity forms block inside Gutenberg editor it shows without problems.
Instead, nothing is shown in the frontend.
If i inspect the source code i can see this comment:
<!-- wp:gravityforms/form {"formId":"1","inputPrimaryColor":"#204ce5"} /-->
I have tried to use the default “twentytwentyfour” theme and it shows in frontend.
Any idea?

Thanks
