Hi Hue Essentials Team,
Since the recent update to version 4.6.4.0 this week, the Hue Essentials UWP app no longer opens on my Windows 10 Pro (x64) PC.
When I click the app icon, absolutely nothing happens—no window appears, and it doesn’t even trigger a classic crash.
I have done some extensive digging in the Windows Event Viewer. Under “Windows Logs → Application”, there is no “Application Error” or “.NET Runtime” error logged at all. The app doesn’t even get the chance to execute code.
However, under “Applications and Services Logs → Microsoft → Windows → AppXDeployment-Server → Operational”, I can see that the package deployment actually succeeds:
“Leistungszusammenfassung des Bereitstellungsvorgangs Register für Paket HueEssentials.HueEssentials_4.6.4.0_x64__yfdreesr38bg8: Overall time: 282 ms”
It seems that right after this quick registration, Windows silently aborts the UI initialization.
I have already performed all the standard and advanced troubleshooting steps, to no avail:
- Repaired and Reset the app via Windows Settings.
- Completely uninstalled and reinstalled the app via the Microsoft Store.
- Cleared the MS Store cache (wsreset.exe).
- Manually re-registered the AppX package via PowerShell (which ran through perfectly fine).
- Restarted the Windows Update service.
- Verified that Background App permissions are fully granted.
- Ran DISM and SFC /scannow to rule out corrupted Windows system files.
Since none of these fixes worked, it strongly indicates that version 4.6.4.0 might have introduced an API call, a new WinUI component, or a Target-Build setting that accidentally breaks compatibility with Windows 10, causing the OS to immediately block the execution.
Since a lot of users are still relying on Windows 10, I really hope this can be investigated and fixed ASAP in a follow-up patch (v4.6.5).
Please let me know if you need any additional system data or logs to debug this!
Best regards,
Martin
