You already have an instance of Wings running through systemd service and are trying to start another duplicate instance, for example by using the commands wings and wings --debug, or another service is using the port.
Use ss -plnt | grep :8080 (or grep :8443 depending on the port) to find what process is currently running and stop it. You can type killall wings to shutdown any ghost Wings process.
