@pifas900, you need to put some effort into writing the issue so the developers have some information to help diagnose the issue.

When does the crash occur?

You have added the category "BattlEye". Is BattlEye crashing or Arma 3?

Have you tried verifying the integrity of the game cache?

Can you prepare and attach a troubleshooting report? Drag and drop the file into the comment box or upload to a free file sharing service and then link to it.
