Description

Environment

  • OS: Windows 11
  • Install path: C:\opencode
  • GUI: Windows Tauri build
  • Bun is available (bun --version works)

Behavior

  • Launching opencode.exe opens a window, but the UI is completely blank
  • DevTools can be opened (F12)
  • No JavaScript errors in console
  • Console only shows decorum logs:
    DECORUM: Waiting for [data-tauri-decorum-tb] ...
    DECORUM: Controls already exist. Skipping creation.
  • Two bun.exe processes are spawned
  • No log files are created under AppData (Local or Roaming)

Expected behavior

  • GUI should load the OpenCode interface

Additional notes

  • opencode-cli.exe works correctly
  • Bun works correctly
  • Running with BUN_DEBUG=1, RUST_LOG, and RUST_BACKTRACE produces no output
  • This looks like the Tauri backend never reaches a ready state on Windows, and errors are swallowed

This issue might be a duplicate of existing issues. Please check:

  • #9577: White screen on launch – OpenCode Desktop (Windows 10) - Similar blank UI symptoms on Windows
  • #11907: WIN10 can't launch opencode desktop - Desktop launch issues on Windows 10
  • #10221: Black screen on just installed opencode - Similar timeout errors and blank screen behavior
  • #12456: Desktop missing Visual C++ Redistributables on Windows - Potential dependency issue affecting Windows desktop startup

Feel free to ignore if none of these address your specific case.
