Hei everyone,
I have the same problem and I try a lot of things and nothing seems to work. I post mine issue here because I don't know where to post it elsewhere.
The crash happens when I launch the game with and without MODS.
The game does work when I launch it in the 32bit version.
The following things are what I have tried already:
Verifying the game files through Steam.
Add -malloc=system to the parameters.
Checked if one of my RAM was broken.
Reinstalled Arma.
Reinstalled C++ redistributables.
Added another Arma3.cfg file.
And other things I can't remember at the moment.
Is there anyone who knows what more I can do?
Many thank you in advance.
Greetz.
