Windows 10: Unable to uninstall Microsoft Store Apps

My WhatsApp and Spotify have stopped working out of nowhere. If I try to run them, nothing happens, no error message or anything like that. Both were downloaded via the Microsoft Store I am regretting it, which makes it annoying to uninstall. I have tried to download these apps straight from their websites to avoid this in the future but both tell me that they are already installed. The Microsoft Store says to "Install" both Spotify and WhatsApp. There is an "Update" button, but nothing happens when I click on it.In Apps & Features, both apps are greyed out. I went into Advanced Options

Uninstalled apps stuck "installing" in Microsoft Store (MSN News)

Hi Will,

A corrupted Microsoft Store cache is one of the possible reasons why some apps are stuck in an "installing phase" when you try to uninstall them. We suggest that you try running the
Windows App troubleshooter to troubleshoot the issue.

If the issue persists, we suggest that you reset the Microsoft Store cache. You can follow the steps below to reset the Microsoft Store cache:

• Press Windows + R keys to open the run
  command box.
• Type WSReset, then try launching Microsoft Store and sign in.

Should you need further assistance, don't hesitate to get back to us.

 

unable to uninstall an app

I had downloaded modern combat 5 game in my phone from the store... But it's not listed in the app list OR it's not there in the start menu..

When I go to store it's showing that the game is installed and gives me an option to view..but when I tap view the store exits..

so I am unable to uninstall it from the phone though it has consumed memory in my device..

Nokia Lumia 730. Any suggestions???
