How to Fix the Call of Duty: Bo6 Dev Error 10493

The dev error 10493 that appears on your screen when you’re playing Call of Duty Black Ops 6 is usually triggered by corrupt game files. The game will load for a while before throwing you back to the opening screen.

You can restart the game or check for updates since beta games tend to have frequent updates critical to the game.

While we can vouch for solution one as being your best bet, it doesn’t guarantee that it will work for you. After all, BO6 is still in the Open Beta phase so a lot of these bugs and problems are common and should be expected.
