Got same issue here, this happened in version 1.4.4. I decided to switch back to 1.4.3 for the moment:
opencode upgrade 1.4.3

同样遇到了这个问题

检查一下是否在项目的.gitignore当中忽略了某个含有大量文件的文件夹, 由于opencode启动的时候会逐个搜集项目忽略文件, 忽略文件一多就会卡死无法启动.

如果清理了gitignore还不行 —— 该问题由4月12日某次提交导致, 可以暂用4月12日前的版本.

Environment:

• OS: Windows 11 Pro
• OpenCode: 1.4.4 (regression from 1.4.3)
• Shell: Git Bash
• Arch: x64

Steps to reproduce:

1. Install opencode-ai@1.4.4 on Windows
2. Run opencode (TUI mode)
3. Type any message and press Enter

Expected: Model responds normally

Actual: Crash with:
ENAMETOOLONG: name too long, uv_spawn
syscall: "uv_spawn",
errno: -36,
code: "ENAMETOOLONG"

  at spawn (node:child_process:679:35)
  at spawn (node:child_process:14:39)
  at dX (B:/~BUN/root/chunk-4j8x370p.js:2:162788)
  at <anonymous> (B:/~BUN/root/chunk-4j8x370p.js:22:18174)

Notes:

• opencode run "message" works fine — TUI mode only
• opencode --pure (no plugins) also fails — not MCP/LSP related
• The crash occurs on message submit, not at startup
• Downgrading to opencode-ai@1.4.3 resolves the issue

Same issue with version 1.4.5, OS Windows 10. Happened on both cmd and WezTerm. I switched back to 1.4.3

Fixed in 1.4.6 via #22560
