APEX LEGENDS ANTI-CHEAT BACKEN CHECK ERROR

There are various issues related to the error "The client failed an anti-cheat backend check", and many users believe the problem has become more frequent after a recent update.

For example:

In Windows environments, some players fixed the issue by disabling overclocking, a solution that was discussed in Korean communities.

Similarly, disabling MSI Afterburner has worked for others.

There are also reports that a recent Discord overlay update may be related to the problem.

And one well-known cause is the presence of Daemon Tools, which can trigger this error.

Additionally, even if reWASD was uninstalled long ago, leftover traces can still be found using tools like Revo Uninstaller, Everything, PowerShell, or pnputil. Some users have claimed that deleting these remnants completely resolved the issue. This is similar to reports from users who said a clean reinstall of Windows fixed the problem—suggesting that these leftovers might be the root cause.

There are also theories that manual server-side reviews may result in users being kicked from matches if their gameplay seems suspicious, even without actual cheats.

What’s certain is that these backend errors have become noticeably more frequent after the recent update.
