Which feature do you enable in the helper add-on?

[jonahspear-toast]

here are my enabled features. Please let me know if there's anything else I can provide

Sorry for this delayed reply. I have come back from my vacation just now. I cannot reproduce your issue. How many times do you meet this error?

It will be fixed in Anki's part: ankitects/anki#3190

I'm not sure if others have encountered the same issue, but I've noticed that when I close Anki, it remains in the background processes. This prevents me from reopening Anki next time, requiring me to manually close Anki from the Task Manager.

I've made several attempts to troubleshoot, and as a conclusion, the error seems to occur during the synchronization process when closing Anki, and it only happens when there's nothing to synchronize.

I've found that commenting out lines 96 and 97 in sync_hook.py can avoid this situation (for testing purposes, not as a solution). This might help in pinpointing the entry point of the problem.

It's a problem related to Orphan Process. FSRS helper add-on runs rescheduling and dispersing in subprocess of Anki. Sometimes the main process of Anki has been terminated, but the subprocess is still running.

Hi there,

For what it's worth, I've also been encountering this issue.

I'm currently using Anki version:

24.04.1 (ccd9ca1a)⁩
Python 3.9.18 Qt 6.6.2 PyQt 6.6.1

where having the add-on enabled prevents Anki from properly closing/quitting. This is on MacOS:

Sonoma 14.5 (23F79)

This issue occurs whether one A) closes via the red "x" button on the top-left of the window, B) closes by right-clicking the app and selecting "Quit", or C) closes by using the Cmd + Q hotkey.

I've confirmed the following other troubleshooting steps, and isolated it to this add-on. FYI, the following add-on also causes the same behaviour, and you can find a submitted bug report here:
