Verify the integrity of game files

As mentioned earlier, a broken update may corrupt your MW3 files. In that case, it is advised to use the file check feature of the platform you play MW3 on. Here is a step-by-step guide for verifying MW3 game files with all the clients on your PC:

Steam

Go to your Steam library.
Right-click on Call of Duty and select ‘Properties’.
Click on ‘Installed Files’.
Select ‘Verify integrity of game files’.

Battle.net

Navigate to the Call of Duty HQ tab in Battle.net.
Select the cog wheel next to the Play button.
Click ‘Scan and Repair’.
Select ‘Begin Scan’ and finally click 'Yes'.

Xbox App

Launch the Xbox App.
Right-click on Call of Duty from the list of installed games.
Select 'Manage'.
Click on 'Files'.
Select 'Verify and Repair'.

Now, the client will run a thorough check of the files and if any broken or corrupted files are detected, the client will automatically download them and replace the ones that are corrupted.

Reset game settings

Sometimes, mismatched game settings can cause a plethora of issues including the MW3 error code 0xc0000005(0) N. To do a proper reset of the game settings, follow the steps below:

First, make sure your game isn't running in the background.
Next, open 'File Explorer'.
Then go to 'Documents'.
Rename the folder 'Call of Duty' to 'Call of Duty_old' as a backup. You may also delete this folder.
Now launch the game.

This should resolve the issue and a new 'Call of Duty' folder should be created with new settings, potentially ridding of the MW3 error code 0xc0000005(0) N.

Turn off overlays

PC gamers tend to run third-party overlays over their games to monitor statistics such as the framerate, frame time, thermals, clocks, RAM usage, and more. However, these tools can conflict with the game and cause it to crash, resulting in an error.

Hence, if you are using any overlays, you should try turning them off. MW3 has an in-game interface option that allows you to track important telemetry and you can use it to monitor your system instead.

That covers all the known possible fixes for the MW3 error code 0xc0000005(0) N. If the error persists despite implementing the abovementioned fixes, it is advised to contact the Activision Support team for further assistance.
