Error when starting Ankit desk

This is only to inform Anki Developer team about an issue I have come across and have resolved.

When starting Anki Desk this morning, the following error appeared:

An error occurred. Please start Anki while holding down the shift key, which will temporarily disable the add-ons you have installed. 
If the issue only occurs when add-ons are enabled, please use the Tools>Add-ons menu item to disable some add-ons and restart Anki, repeat until you discover the add-on that is causing the problem. 
When you've discovered the add-on that is causing the problem, please report the issue on the add-ons section of our support site. 
Debug info:
Anki 2.1.44 (b2b3275f) Python 3.8.6 Qt 5.14.2 PyQt 5.14.2
Platform: Mac 10.15.7
Flags: frz=True ao=True sv=2
Add-ons, last update check: 2021-10-22 08:34:29

Socket error
Traceback (most recent call last):
  File "waitress/", line 121, in handle_write
  File "waitress/", line 259, in _flush_some
  File "waitress/", line 431, in send
OSError: [Errno 41] Protocol wrong type for socket

As a solution, I have clicked the Sync button/link, closed Anki and re-opened Anki: the error has now disapeared.

I hope this helps the Developer team.

Best regards,


It’s probably a timing-related issue
