Reproduction - How did you get this error to appear?
Trying to run a DHCP discover? I modified some of the network settings in the vmx in an attempt to get DHCP to not return 0.0.0.0 I will put my code, map file, and VMX in a github repo, and add a reply once I do.
Version - Were you using the User Kit or Dev Kit? And what User Kit version or Dev Kit commit (Cosmos, IL2CPU, X#)?
Man, not even I know. It's probably the newest user kit? VMWare, VS2022
Neil-Ciciglycerin/GLaDOSOS Repo containing all of my code. The map file was too big, but you should be able to reproduce it by recompiling.
I'mma try updating to the newest devkit to see if that does anything.
The newest devkit is broken.

On the most recent Userkit, it doesn't crash, but just returns 0.0.0.0
I tried changing the connection type to NAT and it didn't do nothing, although it was able to recognize eth0 now.
Nevermind, tried to run it on QEmu, (E1000) it crashed again. What on god's green earth is going on here
Hello! @Neil-Ciciglycerin It's maybe too late... after Installing Devkit, You need to install Cosmos.Plugs in Userkit project. How? : In NuGet Package Manager -> Cosmos Local Feed -> Cosmos.Plugs. Please see this!
I updated the devkit, installed Cosmos.Plugs and it started working.
