[Upgrade]
[Upgrade] Using backward-compatible include order. The latest version of UE has changed the order of includes, which may require code changes. The current setting is:
[Upgrade] IncludeOrderVersion = EngineIncludeOrderVersion.Unreal5_0
[Upgrade] Suppress this message by setting ‘IncludeOrderVersion = EngineIncludeOrderVersion.Unreal5_1;’ in UnrealLearningKitEditor.Target.cs.
[Upgrade] Alternatively you can set this to ‘EngineIncludeOrderVersion.Latest’ to always use the latest include order. This will potentially cause compile errors when integrating new versions of the engine.

This looks like the same problem as Consistent Issue with Builds?
Is there something in common you two have?

The code also didnt work at first with the MovingPlatform telling me that it can’t find it but then the error disappeared. Now im not sure if it is still there or if it recognises it now. I’ve also tried turning off my Firewall and Antivirus, tried reinstalling the .net and verifying unreal engine but nothing worked.

Apologies that this has been overlooked,. I’ve checked the post that @Dan linked and the process was shortlisted in the last post

Uninstalled Visual Studio and .NET
Reinstalled first Visual Studio then .NET
Verified .NET was installed by typing “dotnet --version” in the command prompt
When nothing was found, adjusted PATH in System Environment Variables to have “C:\Program Files\dotnet” above “C:\Program Files (x86)\dotnet” in the list
Verified again with command prompt, this time seeing the installed .NET
Re-Built Project with Development Build Task

Its important to follow all the steps so we can rule this out as an issue.
