I had this problem as well. Delete all .dll files in the ARMA DLL folder, except the readme. Restart STEAM but do not verify game cache.

Could you please upload your crashdumps?
@ajbrutico you can find them under "C:\Users\The Bruticos\AppData\Local\Arma 3" we need the *.mdmp and *.bidmp.

Thank you

seems more of an addon-related crash

Hello,
Thank you for reporting the issue.
We need crash dump files from this folder for solve your problem.
C:\Users\<Name>\AppData\Local\Arma 3\
Can you upload somewhere in winrar package please?
When package will be smaller than 5000k, you can attach it here. When package is bigger, please use some free sharing service and post link here.

How to find correct crashdump file:
Try to make the crash happen
Look into crashdump folder
Upload crashdump with latest date in name (crashdump is rpt + bidmp + mdmp file with same name)
Please don't extract these files as comments, it makes things very messy.

Thank you.

I believe I uploaded dump files, however deleting the .dlls in the DLL folder as SG_Smokintodd noted seemed to work.

This is not a fix, it is a workaround. Any ideas why this would need to be done in order to play the game?

Hi, we are currently analysing the crashdumps.

Ok ty.

Hello,

it seems that some of the dll libraries are corrupted. We are unable to reproducce the problem in our conditions, so I would like to ask you for a cooperation. Please verify your game through Steam, so the dll libraries are downloaded again. ( https://support.steampowered.com/kb_article.php?ref=2037-QEUH-3335 )

Then I would like you to try the allocators one by one to determine which cause the crashes (there may be more of them). To do that please:

Create a shortcut of the arma3.exe file.
Select properties of the shortcut (right click)
To the path of the file, add: -malloc=<dll_name>
it should look similar to this: "C:\Program Files (x86)\Steam\SteamApps\common\Arma 3\arma3.exe" -malloc=<dll_name>

Please, replace <dll_name> with following (one for every launch):
tbb4malloc_bi
tbb3malloc_bi
jemalloc_bi
tcmalloc_bi
nedmalloc_bi
custommalloc_bi

If we could determine which of these are causing the crashes, it would be a big help. Thank you very much!

Hi,
we updated the memory allocators, would it be possible to start Arma on Steam Dev branch?
Thank you.

Hello,
are these crashes happening on current Steam Stable 1.20 version?

No I am not having this crash now.

I also have trouble, sometimes it crashes randomly ingame, sometimes it crashes in the loadingscreen. When it crashes in the loadingscreen it is impossible to join back until the server restarts (maybe something weird in the Server Cache). I reinstalled ArmA3 4 times, including twice through Steam and through the complete windows PC version. None of this fixed the issue for me.

@Skaronator,

yould you please create another ticket regarding your issue?

Thank you very much!
