Widget not loading

Hi! All the avatar widgets I have on my site are missing. They worked before without problem, but now it just shows a blank space.

I'm using Podia, in which you only have to copy and paste the URL of the widget inside a section to work. Other widgets are working fine.

The first image shows the backend. The second one the blank space where the widget should be.

The widget: https://widget.senja.io/widget/161fc46f-d9e5-4871-b769-ffa0794b59c6

My website: www.despeguemusical.com

I have that widget in several landing pages and it's not working in any of them.
