Compatibility Report

  • Name of the game with compatibility issues: Halo: The Master Chief Collection
  • Steam AppID of the game: 976730

System Information

  • OS Version: Windows 11 24H2 (Build 26200.x / ge_release)
  • GPU: HP Victus laptop GPU configuration (hybrid graphics environment)
  • Proton version: N/A (native Windows build)
  • Game Version: 1.3528.0.0

I confirm:

  • [x] that I haven't found an existing report matching this exact crash behavior.
  • [x] that I have checked for Windows, GPU driver, and game updates.
  • [x] that I verified integrity of game files through Steam.
  • [x] that I tested with Easy Anti-Cheat disabled.
  • [x] that I removed overlays and third-party injectors.

Symptoms

Halo: The Master Chief Collection crashes immediately on launch before reaching menus or rendering a game window.

Windows Error Reporting consistently shows:

  • Exception Code: 0xc0000005
  • Exception Offset: 0x00000000020edc7e
  • Faulting Module: MCC-Win64-Shipping.exe
  • Bucket ID remains identical across every crash.

Crash dumps analyzed in WinDbg consistently point to:

AK::SpatialAudio::UnregisterListener

with a null pointer dereference:

Attempt to read from address 0000000000000000

The crash is fully deterministic and identical across launches.

Troubleshooting Performed

The following actions were attempted without changing crash behavior:

  • Reinstalled the game completely
  • Verified Steam game files
  • Deleted MCC AppData/config/cache folders
  • Reinstalled Easy Anti-Cheat
  • Launched with anti-cheat disabled
  • Reinstalled VC++ Redistributables
  • Installed legacy DirectX runtimes
  • Disabled overlays (Discord, RTSS, GeForce Overlay, etc.)
  • Disabled Windows spatial audio
  • Disabled audio enhancements
  • Disabled CFG/DEP mitigations for the executable
  • Forced DX11 launch options
  • Forced dedicated GPU usage
  • Disabled Hardware Accelerated GPU Scheduling
  • Tested with audio devices disabled
  • Rolled back a recent Windows update

Additional Notes

ProcMon traces show no significant DLL load failures, access denied events, or missing runtime dependencies prior to crash.

WinDbg analysis consistently resolves to:

mcc_win64_shipping!AK::SpatialAudio::UnregisterListener

suggesting an internal startup/runtime failure involving Wwise spatial audio cleanup or initialization.

The crash does not occur in:

  • DirectX runtime DLLs
  • GPU driver modules
  • EasyAntiCheat modules
  • system DLLs

Other Steam games launch and function normally on the same system.

Hello @cyrus-rumao, you've come across an issue tracker for a project called Proton. Proton is a compatibility layer to run Windows based games on Linux. Since you're running the game on Windows, Proton isn't involved in any way. This feedback should be directed at the game dev(s).
