Elementor displays in a weird way. A small iframe like on the top left

I have word press latest version and elementor upgraded too but since some weeks ago (even before I did all the updating) I go to the the page I want to edit, click on elementor editting and instead of opening the nice elementor panel I get a page with a small iframe like screen in the upper left corner and some text below. After some seconds that iframe like screen moves tothe bottom and only get a list of items like this:

Menu Cart
Product Title
Product Images
Product Price
Add To Cart
Product Rating
Product Stock
Product Meta
Short Description
Product Data Tabs
Additional Information
Product Related
Upsells
Themovation Elements

Below an example of an URL

I appreciate any support. I have no clue I have even remove one by one in chronological order all the plugins…

Thank you
