[CRASH FIX] 0xC0000005 - STATUS_ACCESS_VIOLATION

I found a way to fix a crash related to memory allocation. If you running Arma 3 on Windows 10 [64-bit] and your game crashing constantly you might try to fix it by following instructions in this tutorial.

I can't guarantee that this will help you but it's worth to try.

How to fix 0xC0000005 - STATUS_ACCESS_VIOLATION

Change the security settings

• 1. Find the game folder (usually located at C:\Program Files (x86)\Steam\steamapps\common\Arma 3)
  
  
• 2. Right click on Arma 3 folder, select Properties and go to the Security tab
  
  
• 3. Click on Edit and give all groups and profiles Full control
  
  
• 4. Click on Apply and go to Advanced
  
  
• 5. Click on Change right next to the Current owner
  
  
• 6. Type in your pc's User Name and verify the name
  
  
• 7. Click on Apply and Close the window.

Try with different memory allocators

• 1. Open Arma 3 Launcher and go to PARAMETERS --> ALL PARAMETERS --> Advanced --> Memory allocator
  
  
• 2. Check how the game works by selecting different memory allocators

Delete Arma 3 directory from AppData folder

• 1. Go to C:\Users\YOUR_USERNAME\AppData\Local
  (To access AppData folder, simply type %localappdata% in Windows Search or press WinKey + R and type it there)
  
  
• 2. Delete the "Arma 3" directory or rename to something else
  (for example "Arma 3 - Backup" just to keep it as backup just in case)
  
  
• 3. Now open the launcher and try again. The "Arma 3" directory will be recreated.

Change Platform to 32 bit

• 1. Open Arma 3 Launcher and go to PARAMETERS --> ALL PARAMETERS
  
  
• 2. Change Platform to 32-bit.
  
  
• 3. Add the -nologs parameter to the Command line.

Restore the parameters to default

• 1. Open Arma 3 Launcher and go to PARAMETERS
  
  
• 2. Click on Restore defaults.

Im running into this same problem and literally tried everything, i then switched the to the Performance build beta and it worked slightly i completed a dynamic recon ops scenario then i tried doing another with a regiment and two tanks then i saved from there, when i loaded my save it crashed on me, with the default test this problem happens constantly when i try to boot it up now whenever i play dynamic recon ops whenever i get into a battle it slows down then crashes

what fixed it for me was unticking the profile folder option

[I'mGoingBerserk]

What fixed this issue for me was going to the parameters in my launcher, going to advanced, checking the box next to Memory Allocator (64-bit) then click the drop down menu, then select JEMalloc allocator, then launch the game.

this error happened to me only when I made a mission basically bot shooting rocket artillery and normal artillery but with a huge amount of ai shooting it and it crashes, what can cause this?

[Reticuli]

Not happy with this.
