Ever sinceElden Ring’sShadow Of The Erdtreeupdate, some players attempting to go on modded co-op adventures have encountered an error message claiming that an undisclosed inappropriate activity was found within the game files. The error kicks players back to the start screen and prevents them from re-enteringElden Ringin online mode.
This is the result of anti-cheat software that can also affect players who are using regular co-op mods, but it’s not meant to mess with players who are joining or being joined by others as the game had intended.

FromSoftware was quick to identify the problem, but has yet to announce an official fix in any of the DLC’s patch notes.
An issue has been identified regarding the PC Version of#ELDENRING.The message “Inappropriate activity detected” may appear without cheating.To fix this issue, please verify the integrity of the game’s files before restarting the game.We apologise for the inconvenience.

Luckily, the developer was quick to share how players could go about to fix the issue themselves. The process is simple, one that many already know as the go-to to fix many of the issues affecting games on Steam.
If you don’t have any mods that the game could flag for this effect, all you have to do is selectElden Ringin your Steam Library, right click on it, then selectProperties. A new window will pop up; select theInstalled Filestab. Next, clickVerify the Integrity of game filesand wait for the process to finish. Everything should be back to normal once you try to play again.

Inappropriate Activity detected on Steam Deck
The official fix doesn’t work on the Steam Deck, and many have complained that they can only play the game in offline mode. Reddit useru/Honeydew-Mainwas able to come up witha fixthat seemingly works for everyone who tried it:
Though this is an anti-cheat function meant to catch players using illegal mods to obliterate anyone unlucky enough to encounter them online, no one has complained about receiving a ban after seeing this error message. The fix is simple, so the biggest problem here is the getting frightened at the notion that the game has (incorrectly) deemed you guilty of some shady practices.

You can now playElden Ring: Shadow Of The Erdtreeon Xbox One, Xbox Series X|S, PlayStation 4, PlayStation 5, and PC.
