Error: Failed to update Minecraft Native Launcher

Hello.

Today when I tried to open the MC launcher it started getting updated and throwed an error message ''Failed to update Minecraft Native Launcher''. 

Yesterday MC launcher worked just fine. I searched into your help desk knowledge base to find some solutions and walked through your troubleshoot method: Minecraft Launcher Troubleshooting FAQ  - Home (zendesk.com) under I'm getting the error 'unable to update Native Launcher.'  But, it did not fixed it.

I'm launching the MC launcher from the MS Store. I tried uninstalling it and reinstalling from your website. But, nothing happened. 

Can you please fix it? I have paid servers up running!!!
