Registration page not showing when using “Studio” layout

Hi,

We create a new Webinar and try to set the registration page. When using the default “Studio” layout we are able to correctly open the Visual editor and define texts and colors and so on.
However, when saving the settings and pressing the registration page button, the page is blank. Inspecting it with Chrome, a couple of errors are shown (see below). It seems it is not able to get a file “wp-webinarsystem/wpws-js/build/static/js/main.9dcb67bc.js.map”. Taking a look at the plugin zip, that file does not exist.

Any thoughts?
