I'm using MySQL(10.4.11-MariaDB) with XAMPP(PHP 7.4.3).
Using phpMyAdmin I try to execute this query: SELECT AES_ENCRYPT("MyText", "key");
As a result I get an error: #2006 - MySQL server has gone away and in XAMPP Error: MySQL shutdown unexpectedly.
In mysql_error.log appears nothing about this.
How to fix this?
UPDATE
I cleared mysql_error.log. Started MySQL, executed query to crash MySQL.
This is content of mysql_error.log:
