Yeah, I get it—that workaround just isn’t viable for you. Honestly, I’d reach out to EA support directly or post a fresh thread to see if anyone’s found a reliable fix. If I were playing BF6, I’d be running into the same issues myself. We’re both stuck in the same boat until Easy Anti-Cheat rolls out a proper update.
What CoPilot has to say about it.
Root Causes of the “EasyAntiCheat_EOSSys does not support bypass IO” Crash
1. BypassIO ConflictsBypassIO is a Windows feature introduced to speed up disk access, especially for NVMe drives.
EAC’s EOSSys.sys driver does not support BypassIO, which leads to system instability or game crashes when the feature is active2.
2. Windows 11 24H2 Update
This update aggressively enables BypassIO for compatible drives.
If you're running this build (e.g., 26100.4652), it may trigger crashes when EAC tries to load during gameplay.
3. NVMe Drive Firmware or Driver IssuesSome NVMe drives (especially Gen 4 or newer) are more prone to triggering BypassIO.
Even if SMART and surface tests pass, firmware-level I/O instability can cause EAC to fail during runtime.
4. DirectStorage Conflicts
DirectStorage, another Windows feature for faster asset streaming, may conflict with EAC’s file system filter.
This is especially problematic in games like Fortnite, Elden Ring, or ARK that use both technologies.
5. DCOM Permission Denials
Event logs often show DCOM errors alongside BypassIO failures.
These permission issues can prevent EAC from initializing properly, leading to crashes
