Fullscreen make the game crash during loading screen

[JamesBind]

Hello !
 
I bought the game via Steam one month ago and it works fine (no problem with full screen) until today :
 
I can chose a world and a level but the game crashes during the loading screen and back to the desktop without any message. I tried to change manually the settings.ini file but same problem.
The only way I have to play is to delete the settings.ini file before I launch the game. Then, the game starts in windowed mode and I can play while I don't try to change to fullscreen mode.
During a level, I can activate the fullscreen mode (with Alt+Enter) and no problem, I can play and finish my level. But in this case, the game will crash (and back to desktop) during the next loading screen...
 
Here is my DxDiag and log files I have (my last game without any problem was the 22th of May).
 
I hope you could help me !
