Symptoms

Starfield crashes consistently when starting a New Game or loading Continue on Linux with an Intel Arc GPU.

The game launches successfully, reaches the main menu, but crashes on New Game / Continue.
The crash occurs regardless of graphics settings and also occurs on a brand-new save.

Proton log shows a fatal:

EXCEPTION_ACCESS_VIOLATION (0xc0000005)
Faulting module: d3d12core.dll

No GPU hang, reset, or device loss is observed in kernel logs (journalctl, dmesg clean).

The game probes NVAPI / DLSS components (nvapi64.dll, sl.dlss*.dll), which correctly report no NVIDIA device and unload.
Disabling NVAPI, DLSS, and Streamline paths does not prevent the crash.

This appears to be a DX12 → VKD3D failure on Intel Arc, rather than a missing library or configuration issue.

Reproduction

1. Launch Starfield via Steam with Proton (Experimental or Proton 10.0-4).
2. Reach the main menu.
3. Click New Game (also reproduces with Continue on an existing save).
4. A loading spinner / loading transition appears.
5. Within ~5 seconds of clicking New Game/Continue, the Starfield.exe process crashes and Steam reports the game has stopped.

Notes

• Reproduces 100% of the time.
• Also reproduces on a fresh install with no mods.
• Changing graphics settings does not affect the outcome.
