Hi, I downloaded open source to build the packaging version of Unreal Engine.
This error occurs when trying to build.
Error CS1069 Namespace 'System.Security' does not have the format 'XmlSyntaxException'. This format was passed to the assembly 'System.Security.Permissions, Version=0.0.0.0, Culture=neutral, PublicKeyToken=cc7b13ffcd2dd51'. Please add a reference for the assembly.
If anyone knows why, please let me know. Thank you.
I searched to download XmlSyntaxException on Nuget, but nothing came up. Something seems to be missing from an existing file, but I can't find a way to recover it.
