[Bug] Windows 10: Models get stuck in thinking status and terminate without response #40486

Description

Environment:

OS: Windows 10 (x64)

OpenCode Version: 1.18.13

Providers tested: OpenCode Zen, GitHub Copilot

Runtimes present: Node.js v24, Python 3.14, Git 2.55

Description:
After initiating any query on Windows 10, no AI model provides an answer. The CLI enters the "thinking/reasoning" state, stays in long execution for a while, and then simply terminates without outputting any response or throwing an explicit CLI error.

Expected behavior:
The model streams or returns a text completion.

Actual behavior:
The process hangs on the thinking indicator for a long period and then gracefully exits with zero output.

Additional Context / Logs:
Running opencode --print-logs --log-level DEBUG shows long pending HTTP/socket connections to background processes before timing out. Cleaning local caches (~/.opencode, AppData\Local\Temp) and re-installing the CLI did not resolve the issue.
