Appears to crash on .BoundToEndpoint(Endpoint) https://github.com/getnamo/UDP-Unreal/blob/master/Source/UDPWrapper/Private/UDPComponent.cpp#L263.

Seems to suggest a missing/malformed endpoint maybe?

Put a breakpoint on that line or line 260 and see what the state of the values are at that point (launch in debugger from visual studio).

Hey, I'm really sorry for the confusion it was my bad the crash was from the IP address. it works fine I just wanted to update this so there is no confusion

Hello @getnamo,Thanks for the assistance! I've opted this for another tool (I've used the PingQoS if you are wondering) as it's more convenient for my use case, many thanks!
