Penumbra BP - Library crash

[Annibale]

Hi everyone
I'm having trouble with Penumbra Black Plague. I arrived at the library and then exit the game. Now, everytime I load my saved game, it crashes. I tried to rollback to a previous saved game, and now, everytime i enter the infirmary it crashes.

I tried to update my graphic card and sound card drivers, delete the settings file and it still crashes.

Here is my hp.log file :
