Complete the Update
So what happen and why this error is popping up? The update for the new maps for the multiplayer mode in your Call of Duty Warzone is not yet installed in your PC, you need to complete the update for it to work.
To do this, go back to Battle.net client, then check for update installation to Call of Duty Warzone. If you recently purchase the base game, you need to wait for the installation to complete.
After the update installation is completed, you can now go back to the game and try the Multiplayer mode.
Already installed the Update, still Getting the Error
You might have corrupt installation files in your Call of Duty directory, you need to repair it for it to work.
You can repair the installation file by going to Call of Duty: MW > Options > Scan and Repair.
Disabling Cache Spot and Sun Shadow
Other method is disabling the Cache spot and Sun shadows in the game settings.
To disable it, you just need to open the game. Then go to Options > Graphics > Aforementioned Settings.

And if that error persist could be that you have bought the base game sooner than warzone than you need to manually download the base game going to your blizzard account there you should able to see the download games. Once you get in the download section you just need to download the base game from there, it will ask you to install battle.net you just need to install it over your battle.net folder, the settings that you have in battle.net wont change after the install the game should started to download the base game. That’s how i fix the error code 6036.
