    Hello.
    Seems there are some corrupted data.
    We would suggest to disable Steam cloud sync, delete DayZ documents folder and then verify the game data. Also make sure everything is up to date.

    Deleted the DayZ folder in Documents, verified game files and disabled cloud saves, relaunched the game, When clicking "Play" OR "Play without mods" after about 15 seconds it shows a black screen for a sec and it crashes again.

    I don't see an option to add new files,
