Can't put featured image or media image only in posts

Hello everyone, this is my first message, I installed the premium version yesterday and I have a problem.
When I want to put a featured image on a page or for example insert an image from the media library everything is fine.

But when I create a post and I want to put a featured image or an image from the media library the button does nothing. It does not open any window to put the images, the option to insert featured image appears but when I click it does nothing, the same with the media library.

thanks to all
