I am also experiencing this issue i have tried and checked everything i know how to do. check drivers, check windows update, uninstall through steam, delete files and do a verification, delete everything manually and redownload, uninstall mods and DLC's and start clean. I've played with administrator settings, I've opened the game using only the Arma3.exe and Battleye.exe nothing has fixed this issue attached are my crash logs and a screenshot of the error that displays. Fun note the error only appears once arma itself tries to open everything else runs fine and no other games are having this issue :( very sad as i had really gotten into this game recently and am really bumed i can't get it to run now
