Problem with Elementor

If I drag and drop GD>listing (from the wordpress list) into an Elementor page block something goes wrong, and the whole page (in the editor only) disappears and shows an email address at the top of the builder. The email appears to be taken from the field of the first listing.
This is making the elementor page builder unusable.
All the other wordpress GD> blocks seem to be fine when dragged into the builder.
Using the HTML field and placing in the GD shortcode for [gd_listings] works fine but obviously doesn’t resolve the shortcode to give a visual of the page in the editor.

Any ideas why this one field is causing this error?
