Python chip-tool issue "zcl NetworkCommissioning EnableNetwork" to device, device enter the network commissioning and success, but when device enter the process of start dns-sd the core panic occured on device.

@Hugh-Bao As per our discussion, can you please clean and re-build the all-clusters-app. Also, there can be some issues with test_event_3.1 branch with Mac (fixed in master #7388 and #7389). I would suggest you to use Raspberry Pi (or Ubuntu Linux) as the controller which would be used during the actual test event.

We're in progress of reviewing older issues. Is this still an issue given how old the SDK this was tested against? Please re-open if so. Thanks!
