commented
1 month ago I created a new project and ported the code over and found that when I send a publish message on a subscribe event it reproduces the issue 100%, as long as I don't publish the message there is no problem. By the way, I just copied the example and changed it.
https://github.com/espressif/esp-idf/blob/master/examples/protocols/mqtt/tcp/main/app_main.c
As soon as the comment switch is turned on, the above problem is reproduced

What is the expected behavior?
system will no reset， and Successful subscription.
What is the actual behavior?
It's still the same after many attempts
Until I commented out the functions
esp_mqtt_client_subscribeandesp_mqtt_client_unsubscribeI've tried building the project after clearing the files, but it doesn't work...
Steps to reproduce.
Debug Logs.
More Information.
there is my code of "mqtt_event_handle"
