Thanks for sharing the details! Try to repair Windows Web Authentication (WebView2)
Feather relies on Microsoft WebView2. If it’s broken or missing, auth fails with “unknown”.
Do this:
- Open Settings → Apps → Installed apps
- Find Microsoft Edge WebView2 Runtime
- Click Modify → Repair
- Reboot your PC
- Try Feather login again
If WebView2 is missing, install it manually from Microsoft (official runtime).
See if this helps. If you need further assistance just let me know.
Best regards,
Kimberly
