@corbindallas, try the below possible solutions one-by-one:

Try restarting your computer and then verifying the integrity of the game cache for Arma 3.

1. Restart your computer and launch Steam
2. From the Library section, right-click on the game and select Properties from the menu.
3. Select the Local files tab and click the Verify integrity of game cache... button.
4. Steam will verify the game's files - this process may take several minutes.

== "C:\Program Files (x86)\Steam\steamapps\common\Arma 3\arma3.exe" -noSplash -cpuCount=8 -exThreads=7 -malloc==malloc -enableHT -maxvram=4609 -noLogs "-mod=C:\Program Files (x86)\Steam\steamapps\common\Arma 3\!Workshop\@CBA_A3;C:\Program Files (x86)\Steam\steamapps\common\Arma 3\!Workshop\@CUP Weapons;C:\Program Files (x86)\Steam\steamapps\common\Arma 3\!Workshop\@CUP Units;C:\Program Files (x86)\Steam\steamapps\common\Arma 3\!Workshop\@CUP Vehicles;C:\Program Files (x86)\Steam\steamapps\common\Arma 3\@Exile;C:\Program Files (x86)\Steam\steamapps\common\Arma 3\!Workshop\@CUP Terrains - Core;C:\Program Files (x86)\Steam\steamapps\common\Arma 3\!Workshop\@Zombies and Demons" -connect=204.12.234.242 -port=2302

Your launch parameters are a bit wonky.

-enableHT should be used without -cpuCount=. Try removing either of the two or remove both.

-malloc==malloc is not a valid launch parameter and can be removed. A valid -malloc would look like -malloc=tbb4malloc_bi.

Issues can occur when -maxvram= is set over 2 GB. Try lowering or remove it.

Please remove -noLogs so that errors may be logged to the arma3.rpt file again.

Alternatively, just reset the launch parameters to their default state via the Arma 3 Launcher. Also check under Steam → Arma 3 → Properties → General → Set Launch Options...

Try repairing the mod(s) via the Arma 3 Launcher:

1. Click "MODS."
2. Click the dropbox arrow next to the mod to repair.
3. Click the "..." icon.
4. Click "Repair."

Try playing without any mods. All three of the arma3.rpt files in the report show that mods were used.

Exception code: C0000005 ACCESS_VIOLATION at 0217C16A

• Try all of the possible solutions listed for 0xC0000005 - ACCESS_VIOLATION on the Arma 3 Unusual process exit article on the Bohemia Interactive Community Wiki.

If the issue persists after trying all of the above possible solutions then use the Arma 3 Launcher to prepare a troubleshooting report and then upload the report to the feedback tracker for the developers to review.

Hi, @corbindallas

Try disable this:

-cpuCount=8 -exThreads=7 -malloc==malloc -enableHT -maxvram=4609

or you can try switch to DEV branch 1.67 and run the game with 64bit client, there is much more vmem space than 32bit and check if the issue still persist.

also, try to delete your profile folder (create a backup) a try to start the game.

The file yourprofilename.vars.Arma3Profile must be deleted.
Path: C:\Users\*username*\Documents\Arma 3

I´ll ask you about sending a new dumps because that you´ve provided had 0 kb size.

Thank you.
