XAMPP MySQL shutdown unexpectedly - no error in logs - mysql

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:
InnoDB: using atomic writes.

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

If your MySql is new without important databases, you can try these steps:
Shut down your Xampp server
Go to C:\xampp\mysql\data directory
delete the ibdata1 file
Restart your Xampp server
Deleting ibdata1 file may destroy your tables, backup everything.

phpmyadmin page is not opening in xampp server

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.
