Hi there! I understand you're on a Windows 11 desktop and after signing into the Healthy Benefits+ Classic app, you faintly see the app but it won't open fully. Let’s work through this to get it running smoothly for you.

First, may I ask a couple of quick questions?
- Are you using the Healthy Benefits+ Classic desktop app installed on your PC or accessing it through a web browser?
- Have you recently updated Windows 11 or the app itself?
- Do you see any error messages or does it just stay stuck on a faint or blank screen?

Meanwhile, here are some straightforward steps you can try to resolve the app not opening after signing in:

1. Restart Your PC: Sometimes a fresh start can clear temporary glitches.
2. Run the App as Administrator: Right-click the app icon and select "Run as administrator" to give it sufficient permissions.
3. Check for App Updates: Open Microsoft Store (if installed from there) and check if updates for Healthy Benefits+ Classic are available; update if yes.
4. Clear Cache and App Data:
- Press Windows + R, type %localappdata% and hit Enter.
- Look for a folder related to Healthy Benefits+ or the app’s developer and delete or rename it to reset app data.
5. Check Windows Compatibility Mode:
- Right-click the app icon, choose Properties > Compatibility tab.
- Try running it in compatibility mode for Windows 10 and see if that helps.
6. Reinstall the App: Uninstall the app completely, then reinstall the latest version from the official source or Microsoft Store.

If none of these steps help, it would be good to also verify your network connection and firewall settings to ensure they’re not blocking the app from loading content after sign in.

Could you please try these and let me know how it goes? If the problem continues, we can explore some deeper troubleshooting or server status checks.

Are you comfortable trying these steps now?
