Hello,
thank you for the feedback.
This error is very generic. It may be caused by many issues, such as a hardware malfunction, a virus in the computer, but also an error in the game itself. Possible solutions:
-Try joining another server, then rejoin the previous one.
-Update the graphics card drivers to a newer version.
-Rollback the graphics card drivers to an older version.
-Check the temperature of your GPUs and CPUs.
-Verify the integrity of the game cache using Steam.
-Re-install DirectX.
-Uninstall the Visual C++ 2013 Redistributable package (x86 version), restart your computer and install the package again (do not use the Repair function).
-Run a Windows System File Check tool to repair corrupted system files.
However, we cannot determine what exactly caused your game to crash. It is necessary you try to run your Arma without any mods. If the crashes still happen then, please send another crashdumps.
If the crashes stop (on Arma without mods), please try to activate mods one by one until you find out which one causes the crashes.
Mods are not official content from Bohemia Interactive and it is very likely that the CTDs you are experiencing are caused by collisions between two or more mods.
Please let us know, thank you.
