Windows 10: Windows 10 apps will not launch

So somehow the apps on my PC didn't want to launch anymore, so I started trying to figure out what the issue was, I've looked at quite a few topics, including ones offsite, and after doing various attempts to fix the issue by reinstalling windows apps with the Appmanifest XML, it still does not work, so I took ownership of the windowsapps folder to manually start some of them, and the windows store app gave me these 2 errors

I'm going to take a guess and I need to have a Full reinstall of the windows store in order for the other apps to work, either that or JUST those 2 DLL files and it theoretically should let me pull up the windows store and update/reinstall apps through the store, I do not want to reinstall windows just so I can use apps again, and have to deal with reinstalling a ton of other programs just to play a handful of games.

Windows 10 Tweaks

As you may already know, Windows 10 (as well as Windows 8) allow you to log in with a valid Microsoft account, instead of creating a local account that only works on your machine. However, you may prefer to keep a local account for privacy reasons. If you do, though, some Windows 10 features—like Cortana—may not work. Despite the default behavior, the Windows 10 Store is not one of them. You can still log in to your Microsoft account for just the Store without switching to a full Microsoft account. The process, however, is not terribly obvious. To do so, follow these steps:

• Launch the Store from your Start menu.
• Click the user icon next to the search box.
• Click “Sign-in” from the menu that appears.
• Choose “Microsoft account” and log in like normal.
• When the “Make it yours” box appears do not enter your password. Instead, click “Sign in to just this app instead.”

Windows 10 Apps are unable to launch

I tried the steps given and restarted my computer. Now I guess its even worse. There is no response at all after I clicked on all those apps, except for the apps that have just reinstalled which I had uninstalled it long ago. Please reply asap.
