Can't pack with everything updated?

Development Platform & Builds

Hello everyone, I come by with an interesting situation that several days of reinstalling, rollbacks and other thingamajigs didn’t help at all: I cannot build anymore with the source engine.

Here’s what is seemingly happening:

  • Recently, Microsoft has flagged more NuGet libraries as unsafe or with security issues, triggering warnings when used.
  • As a result, Unreal Engine source which uses those brand new flags, will output new warnings whenever it uses the SDK of Windows.
  • Because those warnings become errors (internal compiler flag I assume), it gets stuck and gives up trying to read Window’s SDK, thus preventing new builds for Windows as a whole.

Here is how it looks inside of of Unreal Engine source 5.6.1 (No custom code), on a simple project.

Here are my current visual studio modules and such (I only took what was suggested, nothing more):

And here is the error log of “why it can’t pack the project”:

AutomationTool encountered an error before a log file was set, see ‘C:\Program Files\Epic Games\UnrealSauce\Engine\Programs\AutomationTool\Saved\Logs\ErrorLog.txt’ for more details
AutomationTool executed for 0h 0m 2s
AutomationTool exiting with ExitCode=1 (Error_Unknown)

(Yes, my Engine is in a folder called UnrealSauce)

So why can’t Unreal Engine source detect the SDK of Windows?
Any help is welcome.

Hello there @Hugo_Che!

Reviewing your log and screens, even if you are getting the SDK error, I believe the process is not even reaching that step, as you are getting Magick.NET/NuGet warning before that step:

error NU1903: Avertissement comme erreur : Le package ‘Magick.NET-Q16-HDRI-AnyCPU’ 14.7.0 ...

This conflict has popped up in other threads across the community. Due Microsoft latest updates, security is picking these warnings as errors, causing the AutomationTool to fail compilation. There are currently two workarounds for this scenario:

  1. Change your .NET parameters, so the warnings are not treated as errors, via running the following Powershell cmd:
dotnet build -warnaserror-:NU1901 -warnaserror-:NU1903
  1. Update Magick.NET components to their latest release:
  • Go to Engine\Source\Programs\AutomationTool\Gauntlet\Gauntlet.Automation.csproj
  • Update package “Magick.NET-Q16-HDRI-AnyCPU” to the latest version
  • Run the following cmd, and allow the project to rebuild after it’s finished:
dotnet restore Engine\Source\Programs\AutomationTool\Gauntlet\Gauntlet.Automation.csproj

As for your SDK setup itself, from your screens, it seems to be in order. I would review all elements installed, just in case. And for that, you can use UE’s guide on the matter:
