How to Fix Call of Duty: Black Ops 6 Error Codes 0x0, 0x3, 0x5

Call of Duty: Black Ops 6 may encounter error codes such as 0x0, 0x3, and 0x5, causing the game to crash mid-session or prevent it from launching altogether. These errors typically occur when essential files fail to load due to system conflicts, missing resources, or other underlying issues.

• Corrupted game files are a common cause. Damaged or incomplete installations can prevent critical assets from loading properly, leading to crashes or launch failures.
• Conflicting third-party applications, such as game overlays, antivirus software, or background optimizers, can interfere with Black Ops 6’s processes, triggering these errors.

Additionally, insufficient system resources—such as low memory or CPU availability—can cause the game to crash, especially if too many background applications are running simultaneously. Some users have also reported that storing the game in a compressed directory or on an external drive can lead to permission issues or slower execution, further contributing to these errors.

Now that you have identified the causes of the errors, let’s find out how we can fix them with the step-by-step solutions mentioned below, so you can get back to playing the game crash-free.

1. Disable Compressed Content

If the COD: Black Ops 6 folder is compressed, the game will consume significant system resources to decompress assets while running. This can lead to performance issues, including crashes. To resolve this, you can disable the file compression setting for the game folder.

1. Open the Xbox app.
2. From the sidebar, select My Library.
3. Search for Black Ops 6 in your library.
4. Right-click on the game, go to Manage, and then select Files.
5. Click on Browse, which will take you directly to the game’s installation folder.
6. Right-click on the Call of Duty folder and select Properties.
7. In the General tab, click on Advanced.
8. Uncheck the option Compress contents to save disk space under Compress or Encrypt attributes, then click OK to save the changes.

2. Setup Call of Duty Randgrid Service

If Call of Duty: Black Ops 6 crashes immediately upon startup, it may be due to a missing or malfunctioning Randgrid service. This service is a Microsoft Store-related dependency required for launching the game. If you check the error logs, you may see: [Failed to open service atvi-randgrid_msstore (1060)] This error indicates that the system cannot find or access the necessary service. Setting up or reinstalling the service manually can fix this issue.

Note: We recommend you set up a system restore point before applying these commands.

1. Click on the Start menu, type cmd in the search bar, right-click on Command Prompt, and select Run as administrator.
2. Enter the following command and press Enter:

   sc query atvi-randgrid_msstore

   If the service does not exist, you will see the error:

   [1060] The specified service does not exist.

   

3. If the service exists but is corrupted or not functioning, remove it using the following command:

   sc delete atvi-randgrid_msstore

   

4. Manually create the service using the following command:

   sc create atvi-randgrid_msstore type= kernel binPath= "C:\XboxGames\Call of Duty\Content\randgrid.sys"

   (Replace the path with your actual game installation folder.)

5. Depending on your Windows version, use the appropriate command to set service permissions:
   Windows 10:

   sc sdset atvi-randgrid_msstore D:(A;;CCLCSWRPWPDTLOCRRC;;;SY)(A;;CCDCLCSWRPWPDTLOCRSDRCWDWO;;;BA)(A;;CCLCSWLOCRRC;;;AU)(A;;CCLCSWRPWPDTLOCRRC;;;PU)

   Windows 11:

   sc sdset atvi-randgrid_msstore D:(A;;CCLCSWRPWPDTLOCRRC;;;SY)(A;;CCDCLCSWRPWPDTLOCRSDRCWDWO;;;BA)(A;;CCLCSWRPWPLOCRRC;;;IU)(A;;CCLCSWLOCRRC;;;SU)S:(AU;FA;CCDCLCSWRPWPDTLOCRSDRCWDWO;;;WD)

   

6. Once all steps are completed, restart your system and launch Call of Duty: Black Ops 6. The error should now be resolved.

3. Verify Game Files

Missing or corrupted game files are a common cause of crashes in Call of Duty: Black Ops. If certain files become damaged or go missing due to incomplete updates, installation errors, or external modifications, the game may fail to launch or crash during gameplay.

To resolve this, you can use the Verify and Repair tool in the Xbox app. This tool scans all local game files and automatically replaces any missing or corrupted ones, restoring the game’s functionality.

1. Open the Xbox app on your PC.
2. Click on My Library from the sidebar on the left.
3. In your library, search for Black Ops 6.
4. Right-click on the game and select Manage from the menu.
5. In the Manage section, click on File from the top navigation bar.
6. Click Verify and Repair under the options section.
7. Wait for the verification process to complete, then launch the game to check if the issue is resolved.

4. Reset Call of Duty App Data

Corrupted configuration files, improper game settings, or permission conflicts can often cause Black Ops 6 to crash. Resetting the app data removes all stored configurations, forcing the game to generate fresh default settings. This can resolve crashes caused by corrupted files or misconfigured settings.

However, keep in mind that this process will reset all in-game preferences, including graphics settings, control bindings, and other customizations. After the reset, you’ll need to reconfigure these settings manually.

1. Search for Installed Apps in the Windows search bar and open it.
2. In the Installed Apps window, locate Call of Duty and click the three dots next to it.
3. Select Advanced Options from the menu.
4. Scroll to the bottom of the page to find the Reset section.
5. Click the Reset button and wait for the process to complete.

5. Remove Background Applications

Call of Duty’s anti-cheat system is designed to detect and block unauthorized third-party applications, such as reWASD and WeMod, even if they are not directly related to Black Ops 6. These applications often modify input configurations or inject overlays, which can trigger the anti-cheat system and lead to errors or unexpected crashes. If you suspect that these apps are causing conflicts, consider uninstalling them and restarting your system before launching the game.

It’s worth noting that some developers, including those behind reWASD and WeMod, have acknowledged compatibility issues with Call of Duty titles in the past. If uninstalling these apps isn’t an option, check their official websites for updates, as they may have released patches to address anti-cheat conflicts and improve compatibility.
