This error occurs when Easy Anti-cheat files become missing or corrupted. Therefore, it is important to check which files are missing in C:\Users\username\AppData\Roaming\EasyAntiCheat\
(username is your Windows username)
In the case that the AppData folder is not showing up for you, you will need to make sure that Windows is showing "Hidden items" in the folder:
As shown in the image below, this is how normally the EasyAntiCheat folder should look like:
And the GameLauncher folder:
In case you do not have the folder with 19eff97cd1704a3198cd067271dadfbc or your GameLauncher file is empty, then you have to replace the missing files to make sure that your EAC works properly.
To do this, please download the EAC.zip file in the attachment of this article and extract it into the C:\Users\username\AppData\Roaming\EasyAntiCheat folder.
Once you have done that, the issue should be resolved. You can then launch the game and play it without any issues.
