- App version 1.24012.9, Windows 11, MSIX install
- Sequence observed in logs:
13:35:11— preview dev server for a project failed to become ready within timeout (unrelated project, different port than this session's own preview, which stayed healthy throughout)13:35:21—GPU process gone: reason: 'crashed', exitCode: 101457950- Same second — Cowork's persistent RPC connection dies (
failed to read length: EOF, subscriber disconnected) — a symptom of the Electron app itself going down, not an independent Cowork fault 13:36:29— Cowork sandbox VM's graceful shutdown fails, force-terminated (HcsShutdownComputeSystemHRESULT error), cascading further disconnects13:37:40— app restarts fresh- GPU info dump shows both GPUs
active: falseat capture time,glImplementationParts: "(gl=none,angle=none)"— consistent with the GPU process having crashed and not recovered - Workaround in use: avoid preview/design panes on flaky dev servers until fixed
