   Can you share the actual logs? The screenshot shows "Failed to spawn OpenCode Server. Logs:" but the logs section appears empty.

   A few things to check:

   1. Does the sidecar binary exist? Look for opencode-cli.exe in your installation directory (usually %LOCALAPPDATA%\OpenCode or wherever you installed it)
   2. Antivirus/Windows Defender: Check if it's blocking the binary
   3. Run from terminal: Try running opencode serve --hostname 127.0.0.1 --port 4096 from cmd/PowerShell and see if you get any error messages
   4. Logs: Check %LOCALAPPDATA%\opencode\logs or %APPDATA%\opencode\logs for log files

   Also — did 1.1.52 (or earlier) work for you, or is this a fresh install?

   Same here. Earlier version works fine for me. Win10 too.

   1. The binary file opencode-cli.exe exists.

   

   2. I use Windows Defender, I even analyse it, no threat.

   

   3. Running this opencode serve --hostname 127.0.0.1 --port 4096, I get the same UI issue.

   4. No logs in %LOCALAPPDATA%\opencode\logs and %APPDATA%\opencode doesn't exist.

   I also tried 1.1.52, same issue.
   I was running (ok), I think the version was 1.1.48or 1.1.43, after the upgrade to 1.1.53, I get this issue.
   I uninstall it. Try to reinstall with 1.1.53 or 1.1.52 => issue
