With the launch of the Elden Ring Shadow of the Erdtree DLC, many players have encountered the “Inappropriate activity detected” error, and here are some things you can do to fix it.

For most users, this error appears when they try to summon another user. This can be very frustrating, especially when you don’t have any mods installed.

In the meantime, there are a few things you can do to address this issue.

First, make sure your game files are in order and nothing is missing or corrupted. Several users have confirmed that simply verifying the game files through the Steam client can fix the error.

Make sure you are using the latest version of the game. This error is related to Easy Anti-Cheat and an upcoming update should resolve this issue. To ensure Elden Ring is always updated in Steam, follow the steps below.

  • Open Steam, and navigate to your library
  • Here, right-click on “Elden Ring” and select “Properties”
  • In the Updates section, select High Priority under Automatic Updates

Due to this EAC-related bug, the extension also doesn’t work properly on Steam Deck/Linux. Valve is tracking this issue, and the official Elden Ring account has confirmed that they are also working on a fix.

NOTE: Issues with Steam Deck have been discovered and fixes are being developed.

If your Steam Deck is inactive for more than 5 minutes, the game may stop accepting input.

We sincerely apologize for any inconvenience caused.

The date and time of this fix will be announced separately.
