Update GPU drivers and lower some settings
If you have not updated your GPU drivers for a while, now is the moment to do so. Head to the official website of your graphics card manufacturer’s website and look for the model you own. If an update is available, download and install it. After that, depending on the GPU you have, open your GPU software and ensure that the FDR setting (FidelityFX Super Resolution) is not set to Ultra Performance for AMD cards. Similarly, for Nvidia GPUs, go to the Nvidia Control Panel, find the super-resolution setting under RTX video enhancement, and reduce it to 1 or 2 to address the error.

After this, double-click the “COD.reg” file and confirm any prompts.
Launch COD via Steam. This should get rid of the error code.
