Update.
When I replace some of the KA-50 files in the folder "D:\Program Files\Eagle Dynamics\DCS World OpenBeta\Mods\aircraft\Ka-50\Cockpit\Scripts" with the one from "D:\Program Files\Eagle Dynamics\DCS World OpenBeta\_backup.023\Mods\aircraft\Ka-50\Cockpit\Scripts" the game does not crash, but the graphics are messed up.
So from my point of view there was a change in the last update causing the issue?
