UWP App not launching after Windows 10 update

Every time a Windows 10 update is performed on machine with an installed sideloaded UWP app, the app no longer launches and the app needs to be reinstalled. This has become an high issue because we have over 50 machines with the app. What is the Windows update that is causing the UWP app to no longer open? The UWP app was built with version 10.0.19041.0 SDK. I sideload install the UWP app using Add-AppxPackage in Powershell as Admin. The UWP app uses local storage for user profile settings.

When the app can't be launched, are there any errors or exceptions? Could you please open Windows Event Viewer -> Windows Logs -> Applications and check the detailed error message to see what error or exception prevents the app from launching.

Somewhere I learned that UWP app events are found here - Microsoft-Windows-AppXDeploymentServer/Operational

This is what was logged when the app was clicked and would not launch:

Started deployment RegisterByPackageFamilyName operation on a package with main parameter myappnamehere.myapp_ww4kfnnrsedz6 and Options SkipReregisterIfPackageStatusOk, ImmediatePriorityRequest and 0.

And...

AppX Deployment operation failed for package myappnamehere.myapp_ww4kfnnrsedz6 with error 0x80070005. The specific error text for this failure is: Access is denied.

This is the log when you install the app using the script. Please check the log under the path Windows Logs -> Applications.
