Some Sea of Thieves users are seeing the Copperbeard error code while attempting to join or host an online session. Other users are reporting this crash occurs every time they hit the Alt key. This problem is mostly reported to occur for PC Users.

Sea of Thieves Error Code CopperBeard

As it turns out, there are several different causes that might be responsible for the apparition of this error code. Here’s a rundown of the most probable culprits:

  • Server issue – As it turns out, this problem can very well be caused by a server issue that the developer Rare is actively working to resolve. This can either be caused by an internal issue or an infrastructure problem with Xbox Live. In this case, there is no fix of the issue. All you can do is confirm the issue and wait for the involved parties to fix the problem.
  • Game is not permitted to run in the background – The most likely culprit that will cause this problem is an instance in which your Windows 10 computer is not configured to allow the running of background apps. In this case, you can fix the problem by modifying this behavior in order to allow Sea of Thieves to run in the background.
  • Screen size issue – As some affected users have confirmed, this problem can also be occurring due to a screen size issue brought about by a bad patch. If this scenario is applicable, you should be able to fix this problem by switching the game to Windowed mode immediately after it starts.
  • Game file corruption – Under certain circumstances, this problem can also occur due to some kind of corruption originating from the game files that you’re actively storing locally. In this case, a simple reset from the Apps & Features menu should be enough to fix the problem.

Method 1: Checking for Server Issues

Before you move forward to any of the other potential fixes below, start by investigating whether Rare (the game’s developers) is currently struggling with a widespread server issue.

Chances are if the problem is occurring for a lot of users in your area, there is little else you can do to fix the issue other than to wait for the involved developers to fix the problem. Looking at past occurrences, problems of this kind were often caused by inconsistency with the Xbox Live infrastructure with the game server.

To verify whether this is true, start by checking services like IsTheServiceDown or IsTheServiceDown to see if other users are reporting the Copperbeard error right now.

Investigating a server issue with Sea of Thieves

In case you uncover evidence that you might be dealing with some kind of widespread server issue, check the official Twitter account of Sea of Thieves and look for any official announcements on the status of the problem.

Another place where you can look is the Xbox Live infrastructure since the game leverages it to facilitate online interactions on both PC and Xbox One. To do this, check the status of the Xbox Live service and see if there are are any problems currently reported under Games & Apps.

If the investigation that you just performed didn’t uncover any evidence of a server issue, move down to the next method below.

Method 2: Allowing Sea of Thieves to run in the Background

One of the most common instances that will ultimately spawn the CopperBeard error is an instance in which your operating system is not configured to allow Sea of Thieves to run in the background.

Although this doesn’t sound like it should be a problem if you’re actively playing the game, it actually is. This happens because some online services that the game users are treated like background services even if you’re actively playing the game.

Fortunately, you can fix the problem easily by modifying the default behavior in order to allow the Sea of Thieves to run in the background. To do this, follow the instructions below:

  1. Ensure that Sea of Thieves and any background service is closed.
  2. Press Windows key + R to open up a Run dialog box. Next, type ‘ms-settings:privacy-backgroundapps‘ inside the text box. then press Enter to open up the Background Apps tab of the Settings app.
  3. Inside the Background apps tab, start by enabling the toggle associated with Let apps run in the background.

  4. Once the usage of background apps is enabled, scroll down through the list of applications, and locate the entry associated with Sea of Thieves.
  5. When you see it, ensure that the toggle associated with it is enabled (On).
  6. Launch Sea of Thieves once again and see if the problem is now resolved.

In case the same issue is still occurring, move down to the next potential fix below.

Method 3: Running the Game in Window Mode

If the fix above didn’t work for you or the game was already permitted to run in the background, you should turn your attention towards a screen size issue. As it turns out, some affected users have managed to fix this problem by making the switch to window mode.

This is not ideal, but a lot of affected users have confirmed that it was the only thing that allowed them to play the game without encountering the CopperBeard Error.

If you want to give this workaround a try, simply press Alt + Enter immediately after you start the game to make the switch to Window mode. After you do this, attempt to connect online and see if the same problem is still occurring.

If the same error is still occurring even after you made the switch to window mode, move down to the final fix below.

Method 4: Resetting the Game from Apps and Features

If none of the potential fixes above have worked for you, it’s likely that you are seeing this problem due to some type of corrupted game file that’s causing the game to crash. And since Sea of Thieves is installed as a UWP (Universal Windows Platform) application, there is no way to integrity as you would normally do on Steam, Origin or so one.

Fortunately, you can get this problem resolved by resetting the game via the Advanced Options of Sea of Thieves. This was confirmed to work by multiple affected users.

What this operation will essentially do is it will return the game back to its initial state. This means that every bit of cache file, installed the update and account-related data will be cleared.

Note: But don’t worry, there will be no data loss associated with this procedure.

Here’s a quick guide on resetting the game from the Apps and Features screen:

  1. Press Windows key + R to open up a Run dialog box. Next, type the following command inside the text box and press Enter to open up the Apps & Features menu of the Settings app:
    Opening the Apps & Features menu via Run command
  2. Inside the Apps & Features menu, scroll down through the list of installed UWP applications and locate Sea of Thieves. Once you see it, click on it once to expand the context menu, then click on the Advanced Options hyperlink.
  3. Once you’re inside the Advanced Options menu, scroll down to the Reset tab and click on the Reset button.

  4. When asked to do so, confirm the operation and wait for it to complete. Then, open the Microsoft Store and install every pending update of Sea of Thieves before launching it again and launch the game to see if the problem is now resolved.
