Hello I am experiencing recurring Blue Screen of Death (BSOD) errors when launching War Thunder through Steam.

BSOD Error:

  • Bug Check: KERNEL_MODE_HEAP_CORRUPTION
  • Stop Code: 0x13A
  • Parameter 1: 0x11

When does the crash occur?

The BSOD usually occurs during the War Thunder startup process. After launching the game, the BattlEye splash screen or background image appears, followed by a long loading period. Before I can reach the login screen, Windows crashes with the KERNEL_MODE_HEAP_CORRUPTION error.

This issue started occurring after a BattlEye update.

My system specifications:

  • Operating System: Windows 11 26H2
  • CPU: Intel Core i7-13700HX
  • GPU: NVIDIA GeForce RTX 4060 Laptop GPU (8 GB VRAM)
  • RAM: 16 GB DDR5 (2 x 8 GB)
  • Game Platform: Steam

Troubleshooting steps already performed:

  1. Verified War Thunder game files through Steam.
  2. Reinstalled BattlEye components and tested launching the game again.
  3. Temporarily disabled Windows Memory Integrity to test for compatibility issues. The BSOD still occurred.
  4. Ran Windows Memory Diagnostic twice. No memory errors were detected.
  5. Confirmed that Windows Driver Verifier is not enabled.
  6. Examined multiple minidump files using WinDbg.

WinDbg findings:

Multiple crash dumps show the same bug check: KERNEL_MODE_HEAP_CORRUPTION (0x13A), with Parameter 1 equal to 0x11.

The dumps also contain the pool tag “BE__”, but I have not been able to identify the exact driver responsible for the memory corruption.

BattlEye’s kernel driver (BEDaisy.sys) is present on my system. However, I cannot confirm whether it is the actual cause of the crash.

My request:

Could anyone please investigate whether the current BattlEye version has any compatibility issues with my Windows version or system configuration?

I would also appreciate any recommended troubleshooting steps or a possible fix for this recurring BSOD issue.

I can provide the minidump files, WinDbg analysis logs, and additional system information if required.

Thank you for your assistance.

I have the exact same problem since Wednesday.

When I start the game with anti-cheat turned off, the game starts quickly without any issue. But when I close the game, turn anti-cheat on again and then start the game, the same thing happens again.

So it’s clearly a BattlEye problem.

Edit: I’m not playing via steam
