How to Fix “Error Code: 0x00001338” in Call of Duty Vanguard?

Call of Duty Vanguard is the latest game from the CoD franchise, but despite the gameplay and new modes and features, the game comes with a few issues and error codes that the players find annoying. One of the most common error codes that people are encountering is the Call of Duty Vanguard 0x00001338.

This error is happening while they are playing the game, causing it to crash. A message appears on their screen with the error code and a button that is not doing its job to fix the game. This issue is typically encountered on PC.

After many complaints were made by a lot of affected users, we’ve done an in-depth investigation of this error and come up with a shortlist of culprits that might cause this error to occur on certain PC’s:

Now that you are aware of what is making your game to crash repeatedly and act this way, here are some methods that will help you fix the Call of Duty Vanguard 0x00001338 Error for good:

1. Delete Every Activision friend

The first thing you can try is to free up your Activision friend list by deleting a few of your friends. This method doesn’t really have an explanation of how it’s working, but a few players have managed to stop the game from crashing by doing this. 

Note: Most likely, it’s just a glitch that Activision refuses to fix (or doesn’t care about it). This is most effective in situations where you have more than 100 Activision friends on your account. 

You don’t need to delete all your friends from the list, so delete some inactive friends or people that you’ve stopped playing with.

In case you don’t know how to delete your Activision friends, here is a quick guide:

1. Go to the Social menu of your Call of Duty Vanguard account.
2. After that, select the friends that you are willing to remove.
3. Now you need to choose the profile and press Delete.
4. At the confirmation prompt, hit Confirm. 

   

5. After you are done with deleting every player you want to, test the game to see if the error still occurs.

If you’re still seeing the Call of Duty Vanguard 0x00001338 error, go check the next method.

2. Disable Antivirus or Uninstall Firewall (if applicable)

This error might be also triggered by a 3rd party AV or an external firewall. This is happening because the AV or firewall is quarantining some files belonging to the game after a security scan.

If this is the case for you, you can start by disabling the real-time protection of your antivirus.

Most 3rd party antiviruses will allow you to do this directly from the tray bar icon of your AV suite.

In case you are using a firewall and you think that this might be the trigger for your Call of Duty Vanguard error, simply disabling the real-time protection might not be enough to fix the problem since the same security rules will remain in place even after active network filtering is disabled.

In this situation, the only fix is to uninstall the 3rd party firewall conventionally and ensure that you don’t leave behind any files that might still cause this issue:

1. Press the Windows key + R to open up a Run dialog box and type ‘appwiz.cpl’, then press Enter to open up the Programs and Files menu.

   

2. Now that you’re inside the Programs and Files menu, scroll down through the list of installed applications until you locate the 3rd party firewall tool that you want to uninstall.
3. After locating the 3rd party AV, right-click on it and choose Uninstall from the newly appeared context menu to complete the uninstallation.

   

4. Now you need to follow the uninstallation prompts to complete the process, then reboot your PC and see if you still encounter the error.

Move down to the next potential fix in case the error is still occurring.

3. Set Vram usage to 70%

Note: It’s important to understand that the game relies on VRAM a lot, even if the system where Call of Duty: Vanguard runs has a lot of available free RAM. VRAM is just as important of a dependency, but you’ll need to tone it down so that the game prioritizes RAM instead of VRAM.

A few players have managed to fix the Call of Duty Vanguard 0x00001338 error by simply changing the in-game VRAM settings. The setting is by default on 90% usage, but you can fix the error by lowering it to 70%.
