@dosubot[bot] commented on GitHub (Jul 22, 2025):

This issue is likely caused by a frontend state management problem when switching conversations while the AI is still responding. The code is designed to abort ongoing requests and reset state during a conversation switch, but rapid or unsynchronized actions can lead to race conditions or stuck states (dead loops) in the UI. Recent pull requests have improved conversation switching logic, but there is no explicit fix for this dead loop in the documentation or PRs.

I recommend testing with the latest version of Dify, as recent updates have improved related logic. If the problem persists, try collecting browser console logs and network traces when the dead loop occurs to help pinpoint the failure. If you can modify the code, consider adding more robust guard clauses or synchronization in the frontend (for example, in the handleStop or handleChangeConversation functions) to prevent race conditions. If you can share error messages or logs from the latest version, I can help investigate further.

Relevant code and PRs:
