Duplicator causing fatal error

When duplicating a page using the ‘Ex Duplicator’ feature, a fatal error is thrown and WP is unable to show the list of posts. The post is duplicated and appears to be ok from a view within the database. I can also see the duplicated post with wp-cli.

The only solution so far is to delete the post with wp-cli.

WP 6.5.2
Elementor 3.20.4
Exclusive Addons Elementor 2.6.9.3

For what it’s worth, here’s the strack trace from WP. My document root is /local/www/htdocs.
