App Installer app (.msixbundle installer) crashes silently without launching setup windows

I'm trying to install a modern Windows application that comes as an .msixbundle format package. When I double-click the file, a tiny blue circle appears next to my cursor for half a second, and then absolutely nothing happens. No install wizard, no background task error, nothing. My Windows App Installer service seems completely broken. How do I fix it? Thanks.

Hello John Wilson,

To resolve an unresponsive .msixbundle installation, first repair the App Installer by running a re-registration command in an administrative PowerShell window. If the issue persists, verify that the AppX Deployment Service is enabled via the Services console (services.msc). Should problems continue, consult the Event Viewer under Applications and Services Logs > Microsoft > Windows > AppxDeploymentServer > Operational to identify specific hexadecimal error codes that pinpoint the exact cause of the failure.
