I updated to 25.02.4 and now I get 403 unauthorized in the sidebar instead of card info, as well as a pop-up that says “Unexpected API access. Please report this message on the Anki forum”.
Version 25.02.4 (a5c33ad0)
Python 3.9.18 Qt 6.6.2 PyQt 6.6.1
403: <!doctype html> <html lang=en> <title>403 Forbidden</title> <h1>Forbidden</h1> <p>You don't have the permission to access the requested resource. It is either read-protected or not readable by the server.</p>
