C++ QNetworkAccessManager在获取时崩溃

QNetworkAccessManager工作正常，然后每次使用get（）方法时都会崩溃，这非常简单：

QNetworkReply *reply = myManager->get(QNetworkRequest(QUrl(myUrl)));

堆栈如下所示：

QList<QNetworkInterface> interfaces = QNetworkInterface::allInterfaces();

QList interfaces=QNetworkInterface:：allInterfaces（）；

当然，其他团队成员在其他PC和其他地方运行此代码时不会出现问题。原因是什么？！网络问题、防病毒、防火墙（试图在没有运气的情况下关闭两者）等？！为什么它调用QNetworkProxy:：setPassword？！我没有代理，试图显式地设置

NoProxy

，但运气不佳。可能是什么问题？有什么想法吗？

重新安装Qt和creator并帮助重启。

由于“崩溃”（不是一个真正有用的错误描述）来自堆分配器，因此堆似乎已损坏。还有很少其他原因，为什么

RtlpAllocateHeap

会引发SEH异常。由于异常读取访问冲突而在线程5中停止。您尚未修复该错误。重新安装很可能是不必要的。这个问题几乎没有足够的信息来诊断这个问题。这是我目前所拥有的全部，我还看到许多人帮助解决了上述问题。
