Reporting this in a separate thread, since it affects not only to 23.10, but also to 2.166 (and probably previous versions). To replicate:
- Start reviewing any deck
- Open “Previous Card Info” window (Ctrl + Alt + I on Windows)
- Delete the actual note (Ctrl + Del)
- You’ll get an “Error 500: Your database appears to be in an inconsistent state. Please use the Check Database action” error message.
