Form fields not allowing inputs

Hello,

My site has a form inside a modal triggered by clicking on a nav menu′s item but the fields are not allowing inputs and submit button is not processing the order. When clicking on them, the modal seems to fade out and in the end, it fades in. Opening, closing, responsiveness, and styles are fine.

This only happens in that form. There′re other forms on the site but on the page′s bodies, and all working and looking fine. All forms had been built with Elementor (the only editor in usage) and no add-ons.

Theme: Hello. WP, Elementor, and other plugins are updated except EPro (license had expired). I don′t think the license has something to do with this issue because I′ve built other forms after the expiring date and had no problem at all.

If you check the URL, the mentioned modal is triggered by clicking on Contactar nav menu′s item (the last one, on the right).

Anyone knows what could be happening and what to do?

Thanks,

Julia
