Originally created by @rtkelly13 on GitHub (Feb 12, 2026).

Originally assigned to: @rekram1-node on GitHub.

Description

I was developing on two different instances of opencode. One crashed, not sure why, so I restarted the session and got the following error.

spawnSync C:\Users\ryan.kelly\AppData\Roaming\fnm\node-versions\v24.13.0\installation\node_modules\opencode-ai\node_modules\opencode-windows-x64\bin\opencode.exe EFAULT

I resolved it by closing down the other opencode session and running the following

npm uninstall -g opencode-ai; npm install -g opencode-ai

Plugins

oh-my-opencode

OpenCode version

1.1.60

Steps to reproduce

I think this one might be hard to directly reproduce now that I've fixed it.

Screenshot and/or share link

No response

Operating System

Windows 11

Terminal

Windows Terminal

This issue might be a duplicate or related to existing issues. Please check:

  • #11648: [Windows] Upgrade embedded Bun runtime from v1.3.5 — LSP broken due to spawn segfault (similar EFAULT spawn error on Windows)
  • #10007: OpenCode start failed after upgrade (similar failure pattern after upgrade)
  • #12598: After upgrading to the latest version of OpenCode, it won't respond/open (similar post-upgrade issue on Windows)

The EFAULT error in your spawnSync suggests this might be related to the Bun runtime issue mentioned in #11648. If your issue persists, the upstream Bun segfault (oven-sh/bun#25798) may be involved.
