Cannot trash a jevents category using JEvents 3.6.46 on Joomla 3.10.11 using PHP 8.0.26

I can unpublish the category, but when I try to trash I get error:

0 mysqli_fetch_object(): Argument #1 ($result) must be of type mysqli_result, bool given
....../libraries/joomla/database/driver/mysqli.php:894
