Game Crash - Runnable thread OnlineAsyncTaskThreadSteam DefaultInstance crashed.

Thanks again! I have typed your changes.
TESTING

WELL. IGNORE BELLOW. IT COMPILED!

However I haven’t been able to compile since my last post. I can’t seem to add:

#include "OnlineSubsystemSteam.h"

Which has the class FOnlineSubsystemSteam. I get the error " Cannot open include file: ‘OnlineSubsystemSteam.h’ ".

I have tried to look at this thread

But I am being unlucky. The OnlineSubsystemSteam.h path is UE4/Plugins/Online/OnlineSubsystemSteam/Source/Public/onlineSubsystemSteam.h

Would you mind helping with that?

This is what my build.cs file looks like. It’s a Frankenstein and I barely have a clue of what I am doing.

public class MusicalRange : ModuleRules
{
	public MusicalRange(TargetInfo Target)
	{
		PublicDependencyModuleNames.AddRange(new string[] { "Core", 
            "CoreUObject",
            "Engine",
            "InputCore",
			"OnlineSubsystem", //From https://wiki.unrealengine.com/Steam_workshop
            "OnlineSubsystemUtils",
            "Steamworks",            //*/
            "OnlineSubsystemSteam"
        });

		PrivateDependencyModuleNames.AddRange(new string[] {  });

		// Uncomment if you are using Slate UI
		// PrivateDependencyModuleNames.AddRange(new string[] { "Slate", "SlateCore" });
		
		//Uncomment if you are using online features
		PrivateDependencyModuleNames.Add("OnlineSubsystem");

		// To include OnlineSubsystemSteam, add it to the plugins section in your uproject file with the Enabled attribute set to true
		
		PublicIncludePaths.AddRange(new string[] {"Plugins/Online/OnlineSubsystemSteam/Public", "Plugins/Online/OnlineSubsystemSteam/Classes" });
	}
}

Huge Thanks again!
