Use the XAMPP control panel netstat button, or use Windows Ressourcemonitors network tab, or use third party program TCPView, or send a "netstat -aon|find ":3306"" command to get the PID (process ID) and find that PID in your windows task manager processes tab... there are many ways.
Very common this will be another MySQL or MariaDB installation. 3306 is not known for any other famous program tend to use.
