🐛 [firebase_auth] App Builds Successfully but Fails to Launch on Windows 10: Device Loses Connection

[KartikPatelOfficial]

Hi @danagbemava-nc, @Lyokone

Thank you for the updated library. I pulled the latest changes and tried running my app on Windows 10 again. The build completes successfully, but the app doesn't even show a window, and Flutter reports that the device has lost connection.

Here are the final lines from my logs for reference:

I've verified that my Visual Studio installation includes the necessary components for Windows development with Flutter.

Any guidance on resolving this issue would be greatly appreciated.

Best regards,
