Error exporting more than one post or page

When I try to export more than one page or post at a time I get a WP critical error message:
There has been a critical error on your website. Please check your site admin email inbox for instructions.

Single post or page exports work fine. Hoping someone can help. Thank you.

It is working fine at our end. Please ensure that you are using the latest version of plugin with WordPress version 5.3 or higher and PHP version 7.2 or higher. Hopefully it will resolve the issue.

However, if the issue persists, then please enable debugging in WordPress and see if you can capture any details about the issue.
