Editor crashes at opening

[GovRorschach]

WHen I launch the editor, just after creation a new campaign or selecting a previously created campaign (that I never could edit), game crashes and I receive this message :


"Unhandled exception
Exp Code: 0XC000005
ExpFlags: 0
Exp Address : 0X706720BC Please report !"

Here I am.

Windows 10, Asus ROG g551jw
