I have not done anything to Arma to recieve this error. This error popped up out of nowhere and has not been fixed yet. I have literally done everything in the book so don't redirect me to the ACCESS_VIOLATION page on your wiki like many people have been directed to. I went as far as factory resetting my computer. I have no other problems playing any other game, just Arma 3. So it's obviously something to do with Arma 3 and maybe my graphics card conflicting. Remember, I have over 2000+ hours playing Arma 3 and have not had an issue until now. My best guess is it was caused from one of your recent updates.
