It is literally only the Xbox Companion App. All other programs... Save PSO2, of course, work fine.

So in my attempts to download this game, I ended up somehow affecting the Xbox Companion App. Which, apparently, is a requirement to get past the title screen.
I've tried reinstalling, resetting the app. I've tried the same for the Store, too. I've tried downloading and logging into every other Xbox-related app.
Nothing works. I need to fix my access to the Xbox Companion app. How do I go about doing that? I believe I may have changed its ownership but I also tried changing it back. And I don't want to go through any sort of reinstalling of Windows for this.
Please help me. Thank you!
