URL : problem in run URL path after istancing - by: CHRDEI

Good morning,
in my application I properly run a "URL" path with success with this code:

Process.Start(new ProcessStartInfo(e.Uri.AbsoluteUri) { UseShellExecute = true });

After creating a connection with OPCUA server by istancing the EasyClient,
the same code above stops to work and closes suddenly the application (WPF with NET.framework 4..
It happens even after destroying all the OPCUA references.

Please, be so kind to inform me about some ideas.
Tks a lot and best regards

This is the code I use to istance the OPCUA server

private EasyUAClient _Client = null;
private UADiscoveryElementCollection _EndPoint = null;
private UAEndpointDescriptor _endPointDescriptor = null;

if (_Client == null)
_Client = new EasyUAClient();

string uriAdress = (@"opc.tcp://" + _cfgManager.ApplSettings.ServerURI + ":" + _cfgManager.ApplSettings.ServerPort.ToString()).Trim();

_endPointDescriptor = uriAdress;

_EndPoint = _Client.DiscoverLocalEndpoints(uriAdress);
