I recently updated my system to Windows 11 Pro 25H2 and started experiencing crashes in Tom Clancy's Rainbow Six Siege. Every time I try to launch the game, I get a Blue Screen of Death (BSOD) with the stop code KERNEL_SECURITY_CHECK_FAILURE (0x139), specifically pointing to the BEDaisy.sys module. This issue began immediately after the update. Before the update, everything was running smoothly. I've done some troubleshooting, like verifying game files, reinstalling BattlEye, and running diagnostics without finding any issues. Interestingly, disabling BEServices in Steam lets the game launch without crashing. Has anyone else run into this problem or found a fix for the BSOD related to BEDaisy.sys after updating to Windows 11 Build 26200?

It sounds like a tough situation! Make sure to check for any dump files in your system's Minidump folder (C:WindowsMinidump). These files can provide valuable information about what's causing the BSOD. You can zip them up and share them on a file hosting site for someone to analyze. If you haven't already, booting into Safe Mode might help too!
One thing you should definitely do is update all your drivers. Since Windows 11 has shifted how it manages kernel-level access, your anti-cheat software like BattlEye might not be playing nice. Keeping everything up to date could resolve the conflicts.
Thanks for the tip! I’ve already updated nearly all my drivers, but I skipped the BIOS update. Maybe it's worth a shot to update that too.
