mysql error

got this error when trying to add my first event

Hi, perhaps you should try to give much more informations, if you want to get help!

I am not sure what more information I could provide without knowing what you would need. I installed the plugin today on my site. joomla 4 up to date on mariadb latest version, php latest version. I added categories with no issues, added a location with no issue, and the first event I tried to add returned the error I shown in the screenshot.

Hi ,sorry, but don't say latest version, give exact version of joomla, php, JEM...we must try to reproduce your issue. What do you mean with plugin? Perhaps you can give a link to your site.

the website is
PHP 8.2.15
MySQLi 10.11.7-MariaDB-cll-lve
The currently installed Joomla! version is "‎4.4.3"‎

I could go beyond that and give you a back end account

It's rare this error. What are you copying in the description field of event? is text plain or paste from other site?
Could you create a event without any description (empty)? And tell me if the event is create, if not, you could send a capture of this event (config view with the content).
