The game does not start in full screen

I have this problem: I set the resolution in the game, less than the resolution of the monitor, and set fullscreen mode. Everything works fine. But when you reboot the game, it does not open to the full screen. How to fix it?

I did some hack-crutch. But I do not think this decision is right.

void UCustomGameEngine::Init(IEngineLoop* InEngineLoop)
{
	Super::Init(InEngineLoop);

#if UE_BUILD_SHIPPING
	auto GameUserSettings = GetGameUserSettings();
	const auto FullscreenMode = GameUserSettings->GetFullscreenMode();
	const auto ScreenResolution = GameUserSettings->GetScreenResolution();
	const auto DesktopResolution = GameUserSettings->GetDesktopResolution();


	if (FullscreenMode == EWindowMode::Fullscreen)
	{
		GameUserSettings->SetFullscreenMode(EWindowMode::WindowedFullscreen);
		GameUserSettings->ApplyResolutionSettings(false);

		FTimerManager& TimerManager = GameInstance->GetTimerManager();
		TimerManager.SetTimerForNextTick(this, &UCustomGameEngine::HackFullscreenHandle);
	}
#endif
}

void UCustomGameEngine::HackFullscreenHandle()
{
	GameUserSettings->SetFullscreenMode(EWindowMode::Fullscreen);
	GameUserSettings->ApplyResolutionSettings(false);
}
