[BUG]

Title: Cowork sessions crash immediately after SDK auto-update to 2.1.111 — "Failed to create bridge sockets after 5 attempts"

Body:

Summary

Every Cowork session fails with Claude Code process exited with code 1 immediately after sending any message. Started today (April 16, 2026) after the Claude Code SDK auto-updated inside the Cowork VM from 2.1.92 → 2.1.111.

Environment

Claude app version: 1.3036.0
Claude Code SDK version in VM: 2.1.111 (last working: 2.1.92)
macOS 15 (Darwin 25.2.0), Apple Silicon
What happens

The Cowork VM boots fine, network connects, OAuth token is approved, process spawns — then exits with code 1 within ~1 second. 100% reproducible on every attempt.

Error from ~/Library/Logs/Claude/cowork_vm_node.log:

[warn] [vm-stderr] Error: Failed to create bridge sockets after 5 attempts
[info] [Process] Exited, code=1, signal=null, duration=853ms, oom=false
Timeline from logs

Last successful session: April 16 at 13:04 (SDK 2.1.92)
SDK updated to 2.1.111: April 16 at 13:27
All sessions failing since: April 16 at 13:28
Expected behavior

Cowork sessions work as they did with SDK 2.1.92.

Workaround

None available — 2.1.92 binary is no longer cached locally and the VM binary is not available via npm.
