AnkiHub crashes whenever I try to suggest tag updates on

The category for general support questions related to using AnkiHub.

Please include supporting information and documents such as screenshots, recordings, error messages, etc.

Error is as described above. I’m not sure why it’s suddenly stopped working; it was totally fine up until now! The error message is copied below.

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, repeating 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 to the add-on author.
