Art-Net Reader node crashes on node select if port 6454 is taken

If port 6454 is taken by a different UDP Reader node or a 3rd party software, an enabled Art-Net Reader node causes a crash when you select it.

Steps to reproduce

1. Make sure port 6454 is taken (receiving) data either by UDP Reader node or by a 3rd part app.
2. Create an Art-Net Reader node and check its Listening/Streaming checkbox.
3. Select the node.

Workaround

Make sure the port is not taken when you enable Art-Net Reader node.
