Starting to see this issue in the last few days. Things have been running smoothly on J5.1 with php8.2 for months. But now any time I try to save a new field, delete a field, or change the type of an existing field I get this error. The field is still created, edited, or deleted despite the error, well sometimes deleted / sometimes not.

I understand something is going on with the database table. I have deleted any unpublished fields I don't need, changed the field type to text for any field that could work as a text field, and looked through the database table for vchar type field to change to text type, but no luck.  Are there any suggestions for this? Could there be a PHP setting in the Cpanel or a setting in phpmyadmin that will help this out? I'm not exactly sure what's going on here.

Update: mySQL wasn't happy about something in the comprofiler table. I deleted the table and imported another copy and no more issues.
