I have updated the status order in PR https://github.com/openimsdk/openim-sdk-core/pull/417 to try and fix the issue. Meanwhile, I suspect a concurrent scenario where an old connection was being cleared at the same time as the login interface was being called. This could result in the second login referencing the context of the previous connection, leading to a duplicate close. Could you please provide detailed information about your phone model, the operating system version, and your strategy for handling app callbacks in the foreground? Specifically, do you verify the login status before logging in, or do you follow a different approach? This information will help me pinpoint the issue more accurately.

Thank you for your assistance. If the issue persists, please feel free to join our Slack 🤖 for further communication with me.
