Windows 10: Microsoft Store + Microsoft Apps like Calculator do not launch at all.

I have run into a problem after using Revo Uninstaller Helper and presumably deleting registry files that should have not been deleted. Microsoft Store and the Calculator app do not open at all.

How to run apps that are downloaded from Microsoft app store on multiple PCs without downloading multiple times.

 

Microsoft Store will not launch, along with other apps like Calculator

I am running Windows 10 and had to reinstall it (which I've now done 3 times.) The Microsoft Store app will not launch. I can see the app on the start page, but when I click on it or try to use the "open" button, nothing happens. I also have tried to launch
the calculator that comes with Windows and that will not launch either. I have tried many recommended solutions, including:

• The troubleshooter app for Store (reports no issues to be fixed);
• Running the WSReste.EXE to clean out cache (it runs but no errors returned);
• Have reset and terminated in the programs module, with no effect;
• Have used Powershell to reinstall/re-register the app;
• And reinstalled three different times, and immediately following the install, before doing anything else, tested Store with same result.
• Ran SFC /Scannow which runs normally.
• Ran chkdsk /f also no issues (runs on a Samsung EVO).

Am at wits end. I am starting to think there's a virus somewhere, but have done a full scan with McAfee which turned up nothing.

I know there is some connection to my Windows signon; I have signed in with two different accounts, including the one that worked fine before all this nonsense started.

I need some alternative suggestions or other routes to pursue... I don't know where else to go.

At this point, I have version 10.0.19041 installed (Pro.)

All help appreciated!
