Help needed! I am into .pak files to use in my game doing some initial tests and I am not being able to make it work in the editor.

I just cook the assets in the editor using this:

then I go to \saved\cooked\windows<project_name> and there is the Content folder.

I create a temp folder for packing called F:\provi and inside I create the folder and copy the cookec Content folder there.

Using unrealpak.exe from the engine I make my test.pak file

the structure is this:

F:\Provi>unrealpak "F:\provi\test.pak" -list
LogPakFile: Display: Using command line for crypto configuration

F:\Provi>

so I just copy my test.pak file into the project inside /saved/paks/

then I mount the pak running this:

bool UGameInstance_CPP::MountPak(const FString& PakName)
{
    FString PakFilePath = FPaths::Combine(FPaths::ProjectSavedDir(), TEXT("Paks"), PakName + TEXT(".pak"));
    FPaths::NormalizeFilename(PakFilePath);
    
    if (!FPlatformFileManager::Get().GetPlatformFile().FileExists(*PakFilePath))
    {
        return false;
    }
    IPlatformFile& PlatformFile = FPlatformFileManager::Get().GetPlatformFile();
    FPakPlatformFile* PakPlatformFile = new FPakPlatformFile();
    PakPlatformFile->Initialize(&PlatformFile, TEXT(""));
    FPlatformFileManager::Get().SetPlatformFile(*PakPlatformFile);
    if (PakPlatformFile->Mount(*PakFilePath, 0, TEXT("/PakTest/Content/")))
    {
        return true;
    }
    else
    {
        return false;
    }
}

it looks it mounts the pak sucesfully

then I try to get a test asset with this:

bool UGameInstance_CPP::GetAssetFromPak(const FString& AssetPath, UObject*& OutObject)
{
    FString FullAssetPath = FString::Printf(TEXT("/Game/%s"), *AssetPath);
    OutObject = StaticLoadObject(UObject::StaticClass(), nullptr, *FullAssetPath);
    return OutObject;
}

I just get this:

LogLinker: Warning: Failed to read package file summary, the file "/Game/Sound/kiss" is unversioned and we cannot safely load unversioned files in the editor.
LogLinker: Warning: Failed to read package file summary, the file "/Game/Sound/kiss" is unversioned and we cannot safely load unversioned files in the editor.
LogUObjectGlobals: Warning: Failed to find object 'Object None./Game/Sound/kiss'

any clue?
