StaticLoadObject in packaged game

Hello.

I have some code:

for (const FString path : Paths) {


		if (path.Contains(TEXT("forBuildMode"))) {

			if (FPlatformFileManager::Get().GetPlatformFile().FileSize(*path) > 1536) {

				UE_LOG(LogTemp, Warning, TEXT("PATH: %s"), *path);

				FString p = path.Left(path.Find(TEXT("_"), ESearchCase::CaseSensitive, ESearchDir::FromEnd));
				int32 cutLength = p.Find(TEXT("/Content/"), ESearchCase::CaseSensitive) + 9;
				cutLength = p.Len() - cutLength;
				p = p.Right(cutLength);
				p = "/Game/" + p;



				if (!controlArray.Contains(p)) {

					controlArray.Add(p);

					FString pTmp = p + "_Blueprint";

					auto cls = StaticLoadObject(UObject::StaticClass(), nullptr, *pTmp);

					GEngine->AddOnScreenDebugMessage(-1, 5.f, FColor::Green, TEXT("*pTmp ") + pTmp);
					GEngine->AddOnScreenDebugMessage(-1, 5.f, FColor::Green, TEXT("----------------------------- "));

					if (!cls) {
						GEngine->AddOnScreenDebugMessage(-1, 5.f, FColor::Green, TEXT("Failed to load UClass ") + p);
						GEngine->AddOnScreenDebugMessage(-1, 5.f, FColor::Green, TEXT( "*pTmp ") + pTmp);
						GEngine->AddOnScreenDebugMessage(-1, 5.f, FColor::Green, TEXT("----------------------------- ") );
					}

It’s works good, when Game launched from the UE Editor:

But it is not working, when game is packaged:

My pack settings:

and

(tried both variants).

I noticed, that source file and file in packaged game have different sizes (left panel - packaged game, right panel - source files):

Before packaging I run Cook Content for Windows.

What’s happen with my BP after packaging and why it has smaller size after packaging and not working?

Thank you!
