• Enabled G-sync in NVIDIA: If you have enabled the G-Sync feature in your Nvidia Control Panel and on your monitor, the error 6065 might be triggered because this feature is known to cause some issues with the game’s functionality. It is best to temporarily disable G-Sync to fix the dev error 6065 on Call of Duty.
• Wrong names of certain folders in the directory: If some folders in your game installation directory have been named incorrectly, the dev error 6065 might be triggered because the game is unable to find the correct files to load its assets. It is best to get these names right before you play the game.

It is best to have the DirectX 11 enabled alongside with DirectX 12 to ensure complete functionality.
• Enabled Overclocking in BIOS: Overclocking is often used to increase the computer’s hardware performance by pushing beyond the factory limits. It is, however, always recommended to overclock with extra caution to prevent incompatibilities. Therefore, it is best that you temporarily remove your overclock from the Bios and check if that fixes the issue.
