Kicked from server: Anticheat: Corrupt or invalid backend message

I don't know what's going on here. Yesterday it's fine and I can join a game, now I'm kicked from server. Here's the details: "Kicked from server: Anticheat: Corrupt or invalid backend message"Insurgency Error.PNG

I have tried validating game files and restaring my pc but it doesn't works. Please help me resolve this problem, thanks

Just an update from me, I managed to solve this problem after digging the internet.

What I do is repair the Anti Cheat program by running the installer. You can find it on <GameRoot>\EasyAntiCheat\EasyAntiCheat_EOS_Setup.exe

I got this information from this link https://eoshelp.epicgames.com/s/question/0D54z00007JSCRnCAP/meaning-of-eac-error-reason-message?language=en_US
which lead me to this link https://dev.epicgames.com/docs/services/en-US/GameServices/AntiCheat/index.html#windows (this is where I know we can repair the Anti Cheat)

Hope this helps you guys
