Windows 11: GUI opens but stays blank, no logs, bun processes running

[weever99]

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
