Reset-AppxPackage : Package could not be registered.

Remove-AppxPackage : Deployment failed with HRESULT: 0x80073CF6, Package could not be registered. error 0x80070422: Cannot register the request because the following error was encountered while initializing the windows.capability extension: The service cannot be started, either because it is disabled or because it has no enabled devices associated with it.

Resetting an app via Apps & Features might throw the following error:

We couldn't reset this app. Try again in a bit.

The above errors occur if the Capability Access Manager Service (CamSvc) is disabled.

The Capability Access Manager Service provides facilities for managing UWP apps access to app capabilities as well as checking an app’s access to specific app capabilities.

On a default Windows installation, the CamSvc is set to Manual start.

Solution

To fix the Microsoft Store error 0x8D050003 and PowerShell App-Package error 0x80070422, start the Capability Access Manager Service.

1. Launch the Services MMC (services.msc)
2. Double-click Capability Access Manager Service.
3. Set its Start type to Manual.
4. Click Apply, OK.

That should resolve the issue.
