Just tried to use unreal thread it’s doing the same…

here is my code:

uint32 FUdpListener::Run()
{
	//Initial wait before starting
	FPlatformProcess::Sleep(0.03);

	//While not told to stop this thread 
	//		and not yet finished finding Prime Numbers
	while (senderSock->runnable != false)
	{
		CNtlPacket* ptr = (CNtlPacket*)senderSock->m_pNetwork->PeekPacket(senderSock->sock);
		if (ptr != NULL)
		{
			UE_LOG(LogInit, Log, TEXT("Recv data"));
			senderSock->m_recvQueue.PushPacket(new CNtlPacket(ptr->GetPacketData(), ptr->GetUsedSize()));
			FGraphEventRef Task = FFunctionGraphTask::CreateAndDispatchWhenReady([&]()
			{
				HackAndSlash::instance->QueuePacket(senderSock->m_recvQueue.PopPacket());
				HackAndSlash::instance->MyTick();
			}, TStatId(), NULL, ENamedThreads::GameThread);
			senderSock->m_pNetwork->PopPacket(senderSock->sock);
			ptr = NULL;
		}
	}
	UE_LOG(LogInit, Log, TEXT("loop done"));
	return 0;
}

this is the only thing my thread is doing…

Okay i fixed it…

Nothing to see with sound libs, i create a packet on a different thread witch i delete so the at the moment to delete the packet the game crashed, but i don’t know why the sound libs crash…

Anyway fixed.
