Hello, thank you for posting this. We have tried to release several improvements in previous releases. However, we have not been successful in reproducing the issue on our side. Would you be able to share a mini project/code that helps us reproduce this issue?

We found that when we actively called the disconnect method of AWSIoTDataManager, the probability of these crashes occurring would increase significantly. Hope this is helpful for you to analyze the occurrence of bugs.
In addition, when I call the AWSIoTDataManager disconnect method, I'll call the reconnection connectUsingWebSocketWithClientId, whether this would be the cause of the crash occurred probability high?
