[BUG] Claude Code launched via wsl.exe-relayed WSL terminal triggers Windows kernel BSOD (0x1A/0x4477) — safe via SSH-remote WSL session

### Preflight Checklist

- [x] I have searched [existing issues](https://github.com/anthropics/claude-code/issues?q=is%3Aissue%20state%3Aopen%20label%3Abug) and this hasn't been reported yet
- [x] This is a single bug report (please file separate reports for different bugs)
- [x] I am using the latest version of Claude Code

### What's Wrong?

Launching Claude Code from a WSL terminal that Windows opened via `wsl.exe` (e.g. Positron/VS Code's
default WSL-terminal integration) reliably triggers a full Windows kernel bugcheck (BSOD), requiring
a hard reboot. Launching the identical Claude Code binary inside the identical WSL2 VM via an
SSH-remote session (Positron "Remote - SSH" into the WSL distro) does NOT crash, and the native
Windows build launched from PowerShell does NOT crash either. This narrows the trigger to the
specific `wsl.exe`-based interactive console-relay bridge, not Claude Code's memory usage, GPU
usage, or the app itself in general.

### What Should Happen?

Claude Code should start normally regardless of which mechanism was used to open the WSL terminal
session, without triggering a Windows kernel-level crash.

### Error Messages/Logs

```shell
No application-level error — the OS reboots before any error can be captured in Claude Code's own
logs. Windows Event Log evidence:
- Bugcheck 0x0000001A (MEMORY_MANAGEMENT), parameter 1 = 0x4477 (3 of 4 occurrences)
- One occurrence: bugcheck 0x00000050 (PAGE_FAULT_IN_NONPAGED_AREA)
- 4 occurrences over ~3 weeks, each immediately following a `claude` launch in a wsl.exe-relayed
terminal
- Minidumps saved to C:\Windows\Minidump\*.dmp (not yet analyzed with WinDbg — no admin rights on
this domain-joined machine to access the folder)
```

### Steps to Reproduce

1. Open a WSL Ubuntu terminal via a Windows-hosted app that uses `wsl.exe -d Ubuntu -- zsh` directly
(e.g. Positron or VS Code terminal pointed at a Windows-local project, not a remote-SSH project).
2. Run `claude`.
3. Windows reboots (kernel bugcheck 0x1A/0x4477) shortly after launch.
4. For comparison, repeat via a Positron/VS Code "Remote - SSH" session into the same WSL distro:
no crash. Repeat via native Windows build from PowerShell: no crash.

Ruled out as causes:
- reg.exe/Chrome-native-messaging startup path (see #52504) — still reproduces with WSL interop
fully disabled (`[interop] enabled=false` in /etc/wsl.conf, verified via failed `cmd.exe` exec).
- WSL2 GPU-PV — still reproduces with `[gpu] enabled=false` in /etc/wsl.conf.
- Generic WSL2 VM memory pressure — identical Claude Code process runs fine in the same VM when the
terminal session is established via SSH instead of via wsl.exe.

Possibly related: #30137 (closed, not planned — Bun runtime suspected of triggering Windows kernel
BSODs), #32870 (open — claude.exe triggers BSOD via Wof.sys, different/native-NTFS mechanism),
microsoft/WSL#41286 (hvsocket session-transport failures on WSL 2.7.11.0, same subsystem, though
that report doesn't reach full BSOD).

### Additional Information

Claude.ai subscription login (OAuth) — not Bedrock, not Vertex, not a raw Anthropic API console key.

Windows 11 Education, build 10.0.26200, via WSL2 (WSL 2.7.11.0, kernel 6.18.33.2-2, Ubuntu 24.04).
Hardware: dual-GPU laptop, NVIDIA RTX PRO 2000 (Blackwell) + Intel Arc Pro 140T, 64GB DDR5-6400.

Start with the `claude` entry point in a WSL Ubuntu terminal opened through `wsl.exe`, then compare it with the SSH-remote WSL and native PowerShell launches described in the report. Check `/etc/wsl.conf` settings and the Windows Event Log or available minidumps; done means identifying a reproducible application-side cause or showing that the crash remains outside Claude Code.
