I am setting up a new PC with Zoron 18.1. I installed CQRLog and when first launched it crashes trying to create the first database.
I get the following error: "MySql could not be started, please check if MySql Server is installed properly." and "Error during connection to database: TMySQL57Connection : Server connect failed."
From the terminal this is what I get for a MySql Server Status:
mysql.service - MySQL Community Server
Loaded: loaded (/usr/lib/systemd/system/mysql.service; enabled; preset: en>
Active: active (running) since Sat 2026-05-02 05:04:16 EDT; 13h ago

And from the CQRLog error message here's the MySql Error Log:

I could use some help understanding the error log and how do I go about trouble shooting this?
Thanks!
