The game launch on steam, but after some seconds, a window pop up and say: "When the Darkness Come has encountered an error and must close".

He create a report about the error, is very long, but I think what the most important part is here :

When the Darkness comes [version: Unity 2017.3.0f3 (a9f86dcd79df)]

kernel32.dll caused an Unknown exception type (0x20474343) in module kernel32.dll at 0033:7b45318c.
