UI Error 27711 COD Cold War

After we investigated this particular issue, it turns out that there are several different underlying causes that might trigger this error code with Call of Duty: Cold War. Here’s a list of potential causes that might be causing this problem:

  • Outdated COD Cold War version – According to some affected, users, this particular issue is oftentimes caused by a new game update that was pushed while you were spending time inside the menus. In this case, you should be able to fix the issue by closing the game before opening it up again in order to force it to update.
  • Game file corruption – As it turns out, this type of issue can also be caused by some type of game file corruption that is preventing the game from loading certain UI elements in Zombie mode. In this case, you should be able to fix the problem by repairing the game (on Battle.Net) or by reinstalling it (on consoles).
  • Outdated GPU drivers – In case you’re seeing this error code while launching the game on a PC that’s more than equipped to render the game, you should start to consider a driver issue. An outdated or partially incompatible driver might prevent your PC from running the game. In this case, you need to update the GPU drivers using the proprietary updating technology (Nvidia Experience or Adrenalin)

Now that you are familiar with every potential culprit that might be responsible for this issue, here’s a list of verified methods that other affected users have successfully used to get to the bottom of this issue:

1. Update to the latest version of COD Cold War

As it turns out, you can expect to see this error code in those instances where the game developers have just pushed a new update for the Zombie mode. In this case, the error is thrown because there’s a version mismatch that needs to be sorted out.

If you find yourself in this scenario, the only way to resolve this issue is to force the game to update – In most cases, it’s enough to close the game and open it up again (once you re-open it, you will be prompted to update to the latest version available).

Note: If prompts you that there’s a pending update waiting to be installed, don’t launch the game until the updating operation is complete.

Also, if you’re prompted to restart by the game launcher, do so before seeing if the issue was fixed.

Restating the game launcher

Note: On consoles, it’s enough to close the game once and you’ll be prompted to install the update the next time you attempt to open the game.
