WordPress envato elements images blank in media library


I use Envato elements for WordPress, downloading images in the envato elements plugin straight to the WordPress site. Suddenly all images downloaded from the plugin is blank in the media library.
They are fine on the site, and the images are still there if I find the URL in the sourcecode of the site or if I click a blank image and “Edit” it - I see it. This only happened to the images from envato elements, all other images are fine and not blank. Why is this and how do I solve it? (Regenerating the thumbnails did not work :disappointed:) Does anyone know?

Thanks! Kind regards, Annie
