Hello

I am having the same issue in safe mode but in normal mode is just a corrupted screen with loads of colourful lines.

I have reinstalled the game, my drivers are up to date.

This happens when I load the game up on the default prison and when I load a prison of my own.

Removed all saved games from folder and and it still did it.

Can anyone help, I love this game. PS I am not a techy so please put techy things simpler!
