UdpSocketReceiver don't work in build

Hello mates !

I have a problem that I don’t understand, I am currently on version 4.25 (source code).
All worked well in the version 4.22 (source code)

When I use the UDP Receiver, on the editor side the delegate function is called. but when I pass Build, nothing work…
I Added “Sockets”, “Networking” in the PublicDependencyModuleNames in the Build.cs but I dont understand what I miss for the version 4.25 , because actually in 4.22 I have no problem .

Any idea ?

Thank you for your time
