Ankihub plugin not working

2 weeks ago it prompted me to log in to the ankihub addon as I was closing anki for the day so I just exited out, without logging in. Ever since then I receive a bug report when starting the app and am unable to use the ankihub add-on. I have reinstalled anki, deleted and reinstalled the app (with associated folders), and tried changing the driver to software with no luck.

Today I also started getting a bug report for the Amboss addon. I don’t really use the amboss add-on much and my main priority is the ankihub fix.

Anki 25.07.3 (65b5aefd) (ao)
Python 3.13.5 Qt 6.9.1 PyQt 6.9.1
Platform: Windows-11-10.0.26100-SP0
