phpmyadmin page is not opening in xampp server - mysql

I have installed xampp server in my pc. First time creating database and insert data into database using phpmyadmin page was error free. For some table more than 1GB size i changed some configuration file settings like memory_limit, max_data_size. When I restarted the server and open the phpmyadmin page it is showing nothing (no error, no data). I don't understand the problem, already undo all configuration changes but still not working.
In MySQL log getting the following status :

XAMPP MySQL - Crash when execute AES_ENCRYPT

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:

XAMPP MySQL shutdown unexpectedly - no error in logs

XAMPP was working correctly earlier this morning, but after doing some Wordpress plugin updates and resyncing with Github and Pantheon, MySQL now will start, run for a few seconds, and then shut down. When looking at mysql_error.log, I see this:

I don't see any obvious errors.
Any thoughts on how I could either get more detailed error information or how to fix this? Thanks!

In the Windows Event Viewer, I was able to get the following error description:
