Locate the Another World folder in your documents folder and there should be a file called AnotherWorldUserDef. For some reason this file is blank which is why the game crashes at start-up. This is what the contents of the file should look like. Simply copy and paste.

Change to whatever resolution you desire and now the game should no longer crash at start-up. I'm not sure if 4K resolutions are supported. It can't hurt to try.
