code:

FString MountPoint(FPaths::EngineContentDir()); 
	PakFile.SetMountPoint(*MountPoint);

	if (PakPlatformFile->Mount(*SaveContentDir, 0, *MountPoint))
	{
		UE_LOG(YourLog, Warning, TEXT("Mount Success"));
		TArray<FString> AssetsToLoad;
		TArray<FString> FileList;

	PakFile.FindFilesAtPath(FileList, *PakFile.GetMountPoint(), true, false, true);

	FStreamableManager* StreamableManager = new FStreamableManager();
	
		FString AssetName = FileList[10];
		FString AssetShortName = FPackageName::GetShortName(AssetName);
		FString LeftStr;
		FString RightStr;
		AssetShortName.Split(TEXT("."), &LeftStr, &RightStr);
		AssetName = TEXT("/Engine/") + LeftStr + TEXT(".") + LeftStr;
		FStringAssetReference reference = AssetName;

		
		UObject* LoadObject = StreamableManager->SynchronousLoad(reference);
		if (LoadObject != nullptr)
		{
			UE_LOG(YourLog, Warning, TEXT("Object Load Success..."))
			
		}

Hi, did you ever solve the issue ?

I use unreal 4.19.

Make sure *.uasset is cooked ( a.uasset + a.uexp).

Cook file

you can find cooked asset in [Project]\Saved\Cooked dir.

try this AssetName = “/Game/path_to_asset/asset_name.asset_name”
