CS2 crash in scenesystem.dll (0xc0000005) on round start, reproducible #4288
Description
CS2 consistently crashes during round start or within 5–10 seconds after spawning.
Crash always occurs in scenesystem.dll with identical exception code and offset.
This happens on a laptop with hybrid graphics (AMD iGPU + NVIDIA dGPU).
Crash reproduces on both GPUs.
- Launch CS2
- Join any match (Bots / Casual / Competitive)
- Wait for round to start
- Move for ~5–10 seconds
- Game crashes to desktop
Game should continue running normally.
Game crashes with Access Violation.
Windows Event Viewer shows:
Faulting module: scenesystem.dll
Exception code: 0xc0000005
Fault offset: 0x000000000007a767
- DDU clean reinstall of AMD and NVIDIA drivers
- Multiple driver versions
- DX11 and Vulkan
- Running on iGPU only
- Clearing shader cache and user data
- Clean game install
- Launch options: -safe, -novid
- Faulting application name: cs2.exe
Faulting module name: scenesystem.dll
Exception code: 0xc0000005
Fault offset: 0x000000000007a767
Crash offset is identical every time.
Seems like engine-level memory access issue during scene update.
