Hi, I'm Bernard, a fellow Windows user. I'm happy to help!
Since Windows apps are not working, kindly follow the steps below:
Method 1. Repair built-in Windows apps:
Open Terminal (Admin) or Windows PowerShell(Admin) (Press Windows key + X then click Terminal(Admin))
Copy, paste, and enter the command below:
Get-AppXPackage | Foreach {Add-AppxPackage -DisableDevelopmentMode -Register "$($_.InstallLocation)\AppXManifest.xml"}
Then hit Enter. Once the process is done, restart the PC and check.
If none of the above solutions work, I suggest doing an in-place upgrade, which will update the device to the latest version and repair all issues without deleting any files.
Kindly follow the steps from this link:
