no display possible with WP 6.2 and Elementor 3.12.0

Hi, since updating our website to WP 6.2 and Elementor 3.12.0 the plugin doesn’t work anymore. I tried first with the widget which I used before and worked perfect but now I got the link only:
https://boxerclub-bern.ch/wp-admin/post.php?post=447&action=elementor#

Then I tried with the shortcode and got this error message:
The root directory of the gallery couldn’t be found – it may have been deleted or renamed.
In basic options the path is correct.

Thanks for feedback.
