Do you also experience this on Experimental 1.06?
Stop code 0xC0000409 - STATUS_STACK_BUFFER_OVERRUN could mean something is wrong with your game installation.
Try and validate your game files through Steam>DayZ>Properties>Local Files>Verify Integrity of Game Files.
If it still doesn't solve it, when did the crashes start?

I played two years ago. Then everything worked well. I installed the game now and the problem appeared immediately. I played only the main version

Same thing here and no help from devs saying my pc is too old :)
