[Desktop][Windows] UI renders blank "Not found" error on startup after updating to v0.5.22

[paegonza]

Describe the bug

After updating the desktop client to release desktop-v0.5.22 on Windows 11, the application window launches successfully, but the main interface fails to render any content and only displays the error text:

"ERR_FILE_NOT_FOUND"

The app becomes completely unusable. Downgrading back to desktop-v0.5.20 immediately resolves the issue and the interface loads normally.

Steps to Reproduce

1. Install or update to desktop-v0.5.22 on Windows 11 (Buzz_0.5.22_x64-setup_alpha-unsigned.exe).
2. Launch the desktop application.
3. Observe the window frame opens, but the internal canvas/view shows "Not found".

Expected Behavior

The client should connect/load the community view, channels, and local cache as it does in version 0.5.20.

Environment & Details

• App Version: desktop-v0.5.22 (Regression; works on desktop-v0.5.20)
• OS: Windows 11 (x86_64)
• Installation method: Installer / Executable release asset

Additional Context / Logs

• No local UI navigation or reconnect prompt appears, suggesting an internal asset/routing resolution failure (e.g., frontend routing / Tauri webview index load failure) or an unhandled local state migration error between versions.

Same issue confirmed. How do you downgrade?

I downloaded and installed version 0.5.20. The installer suggested deleting the currently installed version 0.5.22, but I chose to keep the previous files, and this restored functionality.
