Blue Screen of Death - Kernel Security Check Failure

When I attempt to start Battlefield 6 Open Beta (tried both Steam and EA launchers) I immediately get a BSOD with Stop Code "KERNEL_SECURITY_CHECK_FAILURE" before the game even starts. Never had this issue with any other game, confirmed other games still run normally.

This is driving me insane, please help!!! Also realize the BF6 beta ends tonight, but I'm worried I'll have the same issue when the full game releases in October so would like to address ahead of that if possible.

Details:

• Bug Check Code = 0x00000139
  • Parameter 1 = 00000000`00000002
    • Stack cookie instrumentation code detected a stack-based buffer overrun (/GS violation)
  • Parameter 2 = fffffe88`2e8eecf0
  • Parameter 3 = fffffe88`2e8eec48
  • Parameter 4 = 00000000`00000000
• Caused by Driver = ntoskrnl.exe (highlighted red in BlueScreenView breakdown of DMP file)
  • Caused by Address = ntoskrnl.exe+4fec10
  • Address in Stack = ntoskrnl.exe+3ab8d8

Unsuccessful troubleshooting thus far:

• Ran launchers (EA and Steam) as Admin
• Forced bf6event.exe and EAAntiCheat.GameServiceLauncher.exe to run as Admin
• Ensured all Windows Updates (including optional ones) are installed
• Updated BIOS (ensured Secure Boot enabled)
• Updated drivers (CPU + GPU)
• Enabled Memory Integrity (via Core Isolation)
• Ran Windows Memory Diagnostic (no issues)
• Ran chkdsk /f (no issues)
• Ran sfc scannow (issues repaired)
• Ran DISM Cleanup Image - Restore Health
• Disabled overclocking (X-AMP in BIOS, MSI Afterburner)
