Per chi può interessare ho trovato la soluzione nel forum di Microsoft Comunity e la risposta è la seguente. Io ho applicato la prima voce che mi ha riparato STORE poi ho disinstallato le APP che niìon funzionavone e reinstallate tramite STORE.
replied on Here are a few that seemed to have help some people with this issue before:
1) Please run the following in a Command Window to re-register the Store app:
"powershell -ExecutionPolicy Unrestricted Add-AppxPackage -DisableDevelopmentMode -Register $Env:SystemRoot\WinStore\AppxManifest.xml"
2)

3) From an elevated CMD you can run "sfc /scannow
4) Check that the file C:\Windows\WinStore\AppxManifest.xml exists and that the contents are:
<?xml version="1.0" encoding="utf-8"?>

5) You can create another user account and see if the issue is the same for that user.
There are just a few things to try that I have found helped other people.
