- Press the Windows key + R to open the Run dialog box.
- Type "wsreset.exe" and press Enter. This will reset the Windows Store cache.
- Restart your computer and try opening the Microsoft Store again.
If the issue persists, you can try the following:
- Press the Windows key + X and select "Windows PowerShell (Admin)".
- Type the following command and press Enter: "Get-AppXPackage -AllUsers | Foreach {Add-AppxPackage -DisableDevelopmentMode -Register "$($_.InstallLocation)\AppXManifest.xml"}"
- Wait for the command to complete and then restart your computer.
Make sure Windows has the latest update and check your time and location settings.
