Getting error STATUS ACCESS VIOLATION 0xC0000005

Happens within or around 30 minutes of play while in multiplayer. Modded or unmodded. Also happens in single player, but takes more time.

This has only happened in the last few weeks. Last time I played ARMA about 1 year ago, there were no issues.

Launcher version: 1.5.146373

Game version: 1.98.146373

Branch: main / beta branch not specified


Operating System
Windows 10 x64
Operating System Version
10.0.18363 Build 18363
Game Crash
Steps To Reproduce

While not purposefully reproduction, it happens every time I play.

Additional Information

I have tried multiple fixes, listed below

Allocating more ram to ARMA in the launcher
Changing the memory allocation system in the launcher
Changing from a 64 to 32 bit platform
adding -nolog to the launch path
adding -malloc=system to the launch path
adding a memory cap to ARMA
Underclocking RAM through BIOS
Reinstalling ARMA
Verifying cache through steam
Reinstalling windows on a fresh drive
Re seating RAM into motherboard
Changing the drive ARMA is on
Lowering graphics settings
Changing from borderless fullscreen to true fullscreen
Uninstalling and reinstalling mods (again, happens without mods too)

And others that I may not be remembering. I have tried fixing this on my own for about three weeks. I figured it would be time to ask for further help

Your RHS is outdated btw.
There are no actual crashdumps in there so I cannot see what causes the crash.
There are lots of very weird network errors, can you try to reproduce it without mods and attach a report of that here?


Please remove that and try the default memory allocator instead.

Thank you for the reply!

Sorry for the late response, I could not get to my computer over the memorial day weekend.

I reset to default parameters in the launcher (memory allocation I believe was one of the only things that was changed) as well as unloaded all of my mods and booted up ARMA. I played most of the way through the infantry showcase mission solo, and crashed when the mortars in the end started to fall, though I have crashed at many different points during this mission in the past.

Again, same error 0xC0000005 STATUS_ACCESS_VIOLATION

Let me know if there are other things, or information that I need to get to you and I can get them to you when I can.

Thank you for your help!

I also think I found my crash dump files from a bunch of my crashes, after I reinstalled windows. I'll toss a bunch of them in here in case you need to look through them.

Still looking for advice on this subject if possible!

Its WIP, I'm just not that fast.
