Description

Summary

On Windows 11 ARM64 hardware, the OpenCode Desktop 1.1.15 x64 build hangs indefinitely on the “Initializing…” screen.
The previous version 1.1.14 works perfectly on the same machine.

This is a version regression, 100% reproducible.

Environment

OS: Windows 11 ARM64

Running: opencode-desktop-windows-x64.exe (via Windows x64 emulation)

1.1.14: ✔️ Works normally

1.1.15: ❌ Hangs forever at "Initializing…"

CLI:

Works if using manually extracted opencode-windows-x64.zip

npm install cannot fetch a working CLI (opencode-windows-arm64 does not exist; opencode-windows-x64 blocked by EBADPLATFORM)

Observed Behavior (1.1.15)

Window appears

UI stuck on “Initializing…”

Never progresses

Must be force-closed

Sometimes re-launches itself due to leftover background process

Expected Behavior (1.1.14)

App initializes in ~1–2 seconds

Providers load normally

No hanging behavior

This is the last log output before the UI becomes stuck indefinitely.

Additional Notes

This regression is not environment-specific — 1.1.14 works reliably on the same ARM64 machine.

The CLI bundled with 1.1.14 worked; removing the 1.1.14 desktop also removed that CLI.

npm fallback cannot install a working CLI:

opencode-windows-arm64 does not exist

opencode-windows-x64 is blocked by platform checks

The break only appears starting in 1.1.15.

Conclusion

OpenCode Desktop 1.1.15 has a startup regression on Windows ARM64 when running the x64 build.
Version 1.1.14 works flawlessly under identical conditions.

A fix in 1.1.16 would be greatly appreciated!

Happy to provide any additional logs or run diagnostic builds.

Steps to reproduce

Install OpenCode Desktop 1.1.14

Launch → Works normally

When prompted to upgrade to 1.1.15, accept

Restart OpenCode Desktop

App now hangs permanently on “Initializing…”

To confirm regression:

Uninstall 1.1.15

Clear state folders:

%USERPROFILE%.local\share\opencode
%USERPROFILE%.cache\opencode
%APPDATA%\opencode

Reinstall 1.1.14 → works again

Upgrade to 1.1.15 → hangs again immediately
