Summary

The Windows desktop app from the latest setup installer exits immediately on launch because the Tauri updater plugin configuration is bundled as null.

Affected version

• LibreFang: 26.6.32241
• Release: v2026.6.22-beta.21
• Installer: LibreFang_26.6.32241_x64-setup.exe
• OS: Windows x64

Reproduction

1. Install LibreFang using the latest Windows x64 setup exe.
2. Launch D:\Programs\LibreFang\librefang-desktop.exe.

Actual result

The app exits immediately with exit code 101:

Starting LibreFang Desktop...

thread 'main' panicked at crates\librefang-desktop\src\lib.rs:532:10:
Failed to build Tauri application: PluginInitialization("updater", "Error deserializing 'plugins.updater' within your Tauri configuration: invalid type: null, expected struct Config")

Expected result

The desktop app should open normally.

Additional context

This reproduced on multiple recent Windows desktop releases:

• 26.6.32179
• 26.6.32190
• 26.6.32241

The source contains updater config in crates/librefang-desktop/tauri.desktop.conf.json, but the release workflow appears to build with only target args and without explicitly passing/merging that desktop config overlay. The updater metadata URL also currently returns Not Found:
