Thanks. HyperTTS looks to be vendoring some third-party code that I’m guessing has broken with the switch to Python 3.13 on Windows. @lucw
The other ones are caused by the add-ons trying to parse the version number instead of using Porting tips for Anki 23.10. If they follow recommended practice, it’ll fix the problem. Those errors won’t happen for stable releases - they’re caused by the beta/rc tag being included in the version number now.
