Activity Detected Error In Elden Ring Shadow of the Erdtree DLC Steam Deck

Play the Game Offline

This isn't the most ideal solution but switching to offline mode can prevent the error from appearing. This means you won't be able to engage in co-op or multiplayer features, but it allows you to continue playing without interruptions from the error message.

Check for Software Conflicts

Certain software or applications could trigger the anti-cheat system erroneously. For instance, uninstalling specific programs like "Direct Folders" may resolve the issue. So check if any newly installed software might be conflicting with the Shadow of the Erdtree anti-cheat system.

Update or Reinstall Game Components

Sometimes, game updates or patches can introduce conflicts with existing game files or software. Ensuring that all your game components and related software are up to date, or reinstalling the game, may resolve these conflicts.

Wait for a Patch

As we mentioned above you might just have to wait for the patch to solve the problem. This isn't ideal but it might be your only option.

Purchase the DLC

Trying to access related content could trigger the error. So if you don't have Shadow of the Erdtree and are trying to access content that requires it you will get this error message sometimes. Especially if you are trying to summon someone or join someone who has the DLC. The game should be showing a different error message in this instance but for whatever reason it shows Inappropriate Activity Detected instead.

What Causes Steam Deck Inappropriate Activity Detected Error in Shadow of the Erdtree?

At this stage, the issue is quite random with some people getting it constantly and some not getting it at all. Despite having the same hardware and game version. This pretty much means the issue is on the developer's end so keep an eye out of game updates that solve the problem.
