Call of Duty: Warzone is an immensely popular game, but it’s not without its problems. Unfortunately for diehard players, most of the game’s error codes result in either crashes or disconnects. Both apply in the case of dev error 6634, which is currently being reported at increasing frequency. This error code tends to appear at the worst possible times, and to make matters worse, it seems to have no discernible cause. What is Warzone dev error 6634, and what can you do to fix it? Read on to learn more.
Call of Duty: Warzone | Dev error 6634
It’s currently unclear what causes dev error 6634 in Call of Duty: Warzone. User reports suggest this error code appears under a variety of circumstances, meaning it’s hard to tell what the true problem is. However, all reports share one thing in common: Dev error 6634 typically results in a total game crash.
Without knowing what causes this error, it’s hard to nail down a fix. There are several reports this dev error code across the Modern Warfare and Warzone subreddits, but none of the posts are able to explain why it occurs. The only real clue is that it seems to appear most frequently following game updates.
Try changing your loadout
However, there is one working theory. Some players have suggested that dev error 6634 is caused by certain Cold War cosmetics and skins. Coincidentally, Warzone players suggested the same issue as the cause behind dev error 6635. Assuming both errors have the same root cause, it’s possible that you could fix dev error 6634 by changing your loadout. Simply remove any Cold War items and see if the issue persists.
With that said, our own readers have suggested that 6635 will still appear without having any Cold War items in your loadout. As is so often the case, your mileage may vary.
It could be a server-side problem
Frustrating as it may be, there is a strange silver lining to this problem. Several users have reported that dev error 6634 crashed not only their game, but also their teammate’s games. In some cases, entire squads have been disconnected simultaneously. Though it may not seem like it, this is good news: Any error that affects multiple players at once can’t be unique to individuals.
If your entire squad gets hit with code 6634, then the problem has to be server-side. Since other users’ systems also crashed, there’s nothing wrong with your game, your console, or your computer. Instead, there’s some kind of malfunction with the game’s code or its connection to servers. That’s good news, since there’s nothing you need to do to fix the problem yourself.
Given all of this evidence, it’s likely that dev error 6634 in Call of Duty: Warzone is a sever-side problem. The only real solution is to wait for the development team to issue a fix. Since most reports of this error appear after recent updates, chances are good it’s caused by some new addition to the game’s code. If you can’t get into the game at all, you should either hold tight for a fix or contact Activision Support directly.
