What's Wrong?

Claude Desktop Code section crashes the entire Electron app every time on Intel UHD 630 hardware.

Crash mode 1 (default launch): GPU process exits with code -1 (4294967295). Crashpad dump ~35MB.
Log: GPU process gone: { reason: 'crashed', exitCode: -1 }

Crash mode 2 (with --disable-gpu): V8 heap reaches 2070MB → OOM in ~17 seconds.
Log: Ineffective mark-compacts near heap limit. Allocation failed – JavaScript heap out of memory

What Should Happen?

Claude Desktop version: 1.6608.2.0 (MSIX, Windows 11 Home 25H2)
Hardware: Acer Aspire TC-886, Intel Core i5-9400, Intel UHD 630 (driver 31.0.101.2141 — latest), 12GB RAM

Problem:
Code section crashes the entire Electron app every time. Two crash modes:

1. Default launch → GPU process exits code -1 (4294967295), Crashpad dump ~35MB

Log: GPU process gone: { reason: 'crashed', exitCode: -1 }

1. With --disable-gpu → V8 heap reaches 2070MB → OOM in ~17 seconds

Log: Ineffective mark-compacts near heap limit. Allocation failed – JavaScript heap out of memory

Attempted fixes (all failed):

• hardware_acceleration_mode.enabled = false in Local State
• TdrDelay = 30 in registry
• --disable-gpu flag
• --js-flags="--max-old-space-size=8192"
• Full reset: Cache, Local Storage, logs, sessiondata.vhdx
• Intel driver already at latest version

Notes:

• Chat section works fine
• Code section worked once (log: VM startup complete, total time: 13639ms)
• CoworkVMService starts correctly when launched manually
• rootfs.vhdx (8.8GB) is intact
