Why isn't AES ENCRYPT and DECRYPT working in xampp mysql? - mysql

Question

I have an sql command like so : INSERT INTO data(pass) VALUES (AES_ENCRYPT('123456',UNHEX(SHA2('my phrase',512)))) and whenever I run it, my sql server turns off and I get the following error : mysql is gone away.
Besides I'm not getting any error with other commands.
This is my log :
