Typically, game crashes are related to the cheat's inability to access memory properly. For this, you will need to check if memory integrity is toggled off in Setup Guide
Some users have reported that memory integrity settings will re-enable after a PC reboot.
If you are having issues with the menu opening or injecting, ensure you have uninstalled all antivirus software, disabled Windows Defender (some users report Windows Defender auto-restarting after a reboot), and have the following drivers downloaded and up to date:
Microsoft Visual C++ Redistributables
Microsoft .NET framework (v8.0) & .NET framework (v4.8.1)
Microsoft DirectX End-User Runtimes
When injecting, the user receives this error:
Check your network and disable any conflicting software such as a firewall or VPN.
Something on your PC or network is blocking our authentication server. This error is typically a software or firewall issue.
uninstall all third-party VPN software
uninstall all third-party firewall software
uninstall all third-party networking software
Sometimes, this is caused by your router or modem configuration.
login to your router and check the firewall settings or any network security settings, parental controls, etc. that may be filtering or blocking traffic
optionally, you can whitelist or "DMZ" your PC in your router (we do not recommend leaving your PC in a DMZ, ever - only do this to test!)
Lastly, this could be your ISP blocking our auth servers.
Install a VPN software such as NordVPN
If all the above solutions do not work, reinstall Windows.
This error is complex, as it is caused by multiple issues. There is no known single fix for this error.
In order and one-by-one, try the following resolution steps:
Disable DLSS Frame Generation, or,
Create a new user in Windows
Return to the Setup Guide and follow all steps
Press start -> type %appdata% -> go up a directory to C:\Users\[username]\AppData, navigate to the Local folder -> look for folders with random lowercase letters -> delete them
In this same directory, Local, look for a folder named loader -> delete the folder
When running the CHARLIE cheat, it generates a random folder name in the Local directory and dumps the loader executable, configuration files, and other necessary files to run the cheat. Sometimes, when the cheat injects, it can hook incorrectly into the kernel of your PC and corrupt itself. By deleting it, you effectively clear this temporary directory to allow the cheat to run "fresh."
Press start -> type documents -> navigate to the Call of Duty directory -> delete the players folder
Follow the steps in Menu & Injection Issues
Press start -> type windows update -> check for Windows updates, also click advanced options and check for optional updates -> install all updates
If using an NVIDIA GPU, press start -> type geforce experience -> click drivers -> in the top right, click the three dots -> choose studio driver -> install these drivers
Reboot PC
In NVIDIA GeForce, the Studio drivers are considered "production-ready" drivers. This means NVIDIA has validated and tested these drivers to be stable.
