Ensure condition failed: !DefaultDomain.IsValid()

The following occurs to us during project startup, it does not crash the editor and it functions fine. It causes cooking to fail. I’ve taken steps to debug this issue and printed the DefaultDomain which trips the ensure. It is Project Content. I’ve also printed some other parts. Here is how it goes. Is it something with our folder structure? I don’t understand since it is completely normal. Any ideas, directions, anything?

Edit: Another funny thing is that unreal plans to crash, but fails to load the crash reporter…
Edit2: It actually fails on “Never Cooked Content” where it doesn’t go through the if it is meant to go through.
Edit3: Solved it, it was my gamesettings.ini. I just removed all the settings and set them by hand again in the editor.

Here is the code for it with my added UE_LOGs in AssetReferencingDomains:

void AddDomain(TSharedPtr<FDomainData> Domain, FStringView RemainingPath)
	{

		int32 DirectorySeparatorIndex;
		UE_LOG(LogTemp, Log, TEXT("RemainingPath: %s"), RemainingPath.GetData());
		if (RemainingPath.FindChar(TEXT('/'), /*out*/ DirectorySeparatorIndex))
		{
			check(DirectorySeparatorIndex > 0);
			const FString DirectoryName(DirectorySeparatorIndex, RemainingPath.GetData());

			TSharedPtr<FDomainPathNode>& ChildFolder = SubFolders.FindOrAdd(DirectoryName);
			if (!ChildFolder.IsValid())
			{
				ChildFolder = MakeShared<FDomainPathNode>();
			}
			
			ChildFolder->AddDomain(Domain, RemainingPath.Mid(DirectorySeparatorIndex + 1));
		}
		else
		{
			if (DefaultDomain.IsValid())
			{
				FString SomeString = TEXT(" ---> ") + DefaultDomain->UserFacingDomainName.ToString();
				UE_LOG(LogTemp, Log, TEXT("DefaultDomain: %s"), *SomeString);
				for (FString stringy : DefaultDomain->DomainRootPaths)
				{
					UE_LOG(LogTemp, Log, TEXT("RootPath: %s"), *stringy);
				}
			}
			if (Domain.IsValid())
			{
				FString SomeString2 = TEXT(" ---> ") + Domain->UserFacingDomainName.ToString();
				UE_LOG(LogTemp, Log, TEXT("Domain: %s"), *SomeString2);
			}
			check(RemainingPath.Len() == 0);
			ensure(!DefaultDomain.IsValid());
			DefaultDomain = Domain;
		}
	}

It was some setting in my defaultgame.ini, I just deleted some odd data registry related lines which fixed it.
