I'm facing a frustrating Blue Screen of Death (BSOD) issue that only happens when I try to launch Rainbow Six Siege. The error appears to be tied to BattlEye, specifically the BEDaisy.sys driver. I've been troubleshooting for a while now, and I'm looking for assistance from anyone well-versed in Windows kernel debugging or conflicts with anti-cheat drivers.
Here are my system specs:
- CPU: Ryzen 5 7600X
- GPU: ASUS GTX 1070 8GB
- Motherboard: Gigabyte B650M D3HP
- RAM: 16GB (2x8GB) Kingston Fury Beast DDR5 5200
- PSU: Gigabyte 850W Gold
I'm running Windows 11 Pro, Build 26200. The issue occurs every time I launch the game—the system freezes and then crashes with a BSOD. The bug check is 0x139 KERNEL_SECURITY_CHECK_FAILURE, with the subcode indicating a FAST_FAIL_CORRUPT_LIST_ENTRY.
WinDbg analysis consistently points to the BEDaisy.sys file causing the issue. I've made several attempts to fix this, including updating my BIOS, reinstalling the game and BattlEye, disabling various virtualization features, and ensuring clean driver installs. Despite all this effort, the BSOD still occurs consistently at the same point in the BEDaisy driver.
I've included a link to the minidump file for more insights. Has anyone encountered this specific problem with BattlEye, or could another kernel driver be messing with it? I'd greatly appreciate any ideas or debugging suggestions. Thanks!

I haven’t experienced this exact issue, but since BattlEye operates at the kernel level, conflicts might arise from other anti-cheat programs or even antivirus software viewing it as a threat. If you're using a third-party antivirus, try adding BEDaisy.sys to your whitelist.
Additionally, you might want to uninstall and reinstall the game since that could help resolve any conflicts or restore a faulty driver. Just make sure to post your issue in more relevant communities like game-specific forums or Windows support groups for more targeted advice.
Where is BEDaisy.sys located on your system? That might help to pinpoint the issue. If it's in the usual spot—C:Program Files (x86)Common FilesBattlEye—then at least we know that's not changed. Finding it there is good, as it means the file should be properly installed.
