Game crashes after activating silo fan.

Hello. For some reason, the game crashes just after I activate the giant fan inside the silo. Even after turning all the settings as low as I could, it still crashes mere seconds after activating the fan. I have attached the MDMP file, As requested in one of the pinned topics. If you need any more information, such as my computer specifications, I would be happy to give any more info needed to help fix this issue. Any help is appreciated.

Thank you in advance.
