macos Crashed ！When switching networks, it crashes. QRingBuffer::clear()

When switching networks, it crashes.

For example, when I first use a WiFi network and switch to a mobile hotspot network, there is a certain probability that this problem will occur.

My network program is simple after all, just set up an Udp server to listen for packets from network ports, that's all. I suspect that there may still be some message bugs in the Qt framework for the macOS network, rather than issues with my programming usage.

If you cannot solve the problem temporarily, do you have any programming suggestions?
