When a modern application does not load (does not run) or ignores your order to close, you may simply need to re-register it Windows to fix the problem.
Now we'll show you how to re-register all modern apps you've already installed in a user account in Window 8 or Window 10.
1. Open it PowerShell. To do this press the 2 Win + R keys at the same time and in the new “Run” window that will appear write Powershell.exe and press key OK.
This command will run Windows Powershell, that is, it will open a new dark window blue colored like the Command Prompt window (Command Prompt).

2. In PowerShell, copy and paste the following command, and then press Enter. (See the picture below)
Get-AppXPackage | Foreach {Add-AppxPackage -DisableDevelopmentMode -Register "$ ($ _. InstallLocation) \ AppXManifest.xml"}
3. When finished, close it PowerShell, and try resubmitting the problematic modern app.
Good luck
