Sorry to hear this mod is causing you issues.
Can you provide more information what you mean with 'crash'? Is there some error?
Note that the screenshot are taken by Factorio itself (not the mod), and it can handle only a certain maximum size. Depending on your RAM (memory) and the limitation that are set by the game.
The mod should handle the limitation set by the game, so I suspect you are out of memory to take the screenshots (without more details of the crash, this is only speculation).
