So, how do I fix this ?

MySQLcould not be started on latest Linux mint.

Reason shows up on your first line: [Server] /usr/sbin/mysqld (mysqld 8.0.32-0ubuntu0.22.04.2) starting

Cqrlog needs MariaDB if you are using the default log database base (in your home folder) that is "save log data to local machine"
install mariadb packages: server, client and compat
Installing them will remove mysql 8

You can use Mysql 8 if you use it without "save log data on local machine" and set sql server address as localhost, port 3306 (in Database connect window) and create sql user with password and privileges to create an modify databases and set that information also to database connect window.


That fixed it! Thank you!
