While playing a cutscene I couldn't get out of it and had to restart, then when I tried to change the game from full-screen to window, I double clicked and set it back to full-screen, effectively freezing my computer and so i had to Shut Down and Reboot.
It's the first big monster, a werewolf(?). I was running the game on Windows 10.
Also it's entirely possible your game may have messed with my Computer Monitor's settings? After the crash, I've noticed that my monitor, when it goes into sleep mode, doesn't fully shut off. To further elaborate, the power light when the monitor is "Awake" is green. and it turns orange when in sleep mode. However, when my monitor goes into sleep mode it goes black but the screen is still lit up, that is to say it shows a black screen to say it's gone into sleep mode when it hasn't, as the power light is still green. It's very bizarre, and I want to know whether or not your game may have done something damaging to my computer.
