Client kicked by EAC: Corrupt or invalid backend message

I am writing to request assistance regarding an issue where a client was automatically removed from the server by the anti-cheat system.

The logs indicate the following message:
“ActionReason: 2 - Details: Corrupt or invalid backend message”

Client ID: krtest004
ClientHandle: 0000000003967D8
Date/Time: 2025/06/02 11:54:26 (UTC+X)
Platform: [e.g. Windows / Steam / Epic Games Launcher]

We would like to better understand what may have caused this action and whether it is due to client misbehavior, corrupted data, or a possible false positive.

Please advise us on how to proceed, and let us know if you require additional logs or diagnostics from our side.

Thank you for your support.
