I can confirm the issue. Interactive lessons in Study Mode are currently broken when Lichess Tools is enabled.
On Brave (Chromium 140.0.7339.186) the study freezes after 2 to 3 moves in interactive mode.
On Firefox 143 the prc: values are ignored and it always follows the main line instead of using the weighted probabilities.
When I disable the extension everything works normally but without the extra features.
So it seems directly related to the latest version of Lichess Tools.
Thanks Siderite for all your great work on this project, it is really appreciated.
