I'm pretty far from being a C++ expert, but I think this may be due to holding a reference to the Config beyond it's lifetime?

See StartDiscovery(): https://cs.android.com/android/platform/superproject/main/+/main:packages/modules/adb/client/transport_mdns.cpp;drc=2c73f5abdf31943e12c68e75f8148c10d2abbf6a;l=154?q=transport_mdns.cpp&ss=android

void StartDiscovery() {
    ...

    g_state->task_runner->PostTask([]() {
        //  optional<Config> created here
        auto config = GetConfigForAllInterfaces();
        if (!config) {
            return;
        }

        // long-lived reference of config given to OpenScreen
        g_state->service = discovery::CreateDnsSdService(g_state->task_runner.get(),
                                                         g_state->reporting_client.get(), *config);

        for (int i = 0; i < kNumADBDNSServices; ++i) {
            auto receiver = std::make_unique<ServiceReceiver>(
                    g_state->service.get(), kADBDNSServices[i], OnServiceReceiverResult);
            receiver->StartDiscovery();
            
            ...
        }

       ...

       // config destructed here
    });
}

A word on impact:

• We rely on WiFi debugging because we use the USB port for additional devices.
• This has made WiFi based debugging unreliable and painful to use because when ADB crashes the connection is lost and is not automatically re-created. Often it can required manually toggling WiFi debugging on the tablet.
