I don't know why the anti-cheat operation failed. Yesterday, I was able to play normally, and I verified the integrity of the game again. However, when playing, I still received a prompt saying "The client anti-cheat system failed to run an integrity check." (CM: Edited to remove additional language. Provided Google Translate version for prompt quote. Please only post in the language of the board per forum rule.)

for anyone still having this issue who, to their knowledge, doesn't use cheats or remapping software: I fixed mine by uninstalling the copy of rewasd that had been sitting untouched on my PC for years. It seems EAC is sniffing for that exe's presence on your PC, rather than checking that it is currently running.

I have the same issue since this morning, didn't happened yesterday.
I tried all the solutions listed previously and didn't work for me.

I'm currently reinstalling hoping it will be fixed.

Hi folks,

Can I check if you are still encountering this? Could you try loading up a match again?

Yes - it's still an issue. I had a problem yesterday and doing the easyanticheat verify and reinstalling the anti-cheat files via steam seemed to work. but - getting the same error today and the same fix has not helped so - I suspect yesterday's fix was a coincidence.

Can play a match for about 5 minutes then...get the error and get kicked

Hello,

Thanks for checking and sharing the steps you've already tried. It helps rule out some things.

If you have 3rd party apps that might be running in the background, could you disable them and test this again?

This guide will outline how:
