Character movement problems (The Dark Eye: Memoria)

Steam version of the game.
At the end of the second chapter, when we start playing as Siju, she suddenly stops moving. Stuck in the area of ​​a trap that needs to catch a rabbit. Reacts to the right mouse button (inspect an object), but does not walk. The inventory also works and things can be taken from it, but the character does not move.
I tried reinstalling the game, checking the cache, nothing helps. What to do?((
