Here a little help for solving Windows store problems for all who tried to change region/ time zone and that somehow messed up your store:

1. Type Powershell in Windows Search. Right-click and select Run as administrator.

2. Type in the following command in the Powershell “Get-AppXPackage | Foreach {Add-AppxPackage -DisableDevelopmentMode -Register “$($_.InstallLocation)\AppXManifest.xml”}”
3. Restart your PC after this process ends.

Fix: Microsoft Store missing in Windows 10

If you’ve updated to the latest version of Windows 10 and Microsoft Store is missing, you may need to reset the Store, tweak the system settings or you can read our article to learn the process step by step.

After that, Store downloaded the MSFS launcher again and let’s you know that you will be able to install it properly once it becomes available in your region.

And very special thanks to @DiscreteDeer236 who with his previous post made me google how to fix the store.
