Microsoft Store -- Game suddenly won't launch after many hours

[Sorcel]

Is anyone else seeing this issue? I bought the game on the Microsoft Store (outright, not via Game Pass) on launch day, and have played for a few dozen hours. All of a sudden, as of today, it wouldn't launch. I got an "This app encountered a problem" message asking me to reinstall. I clicked reinstall, and a very quick download bar popped up, followed immediately by a "complete" message -- and the game *still* wouldn't launch.

I checked my Windows version -- it's 1909.

I tried uninstalling, rebooting, and reinstalling. Same download bar, same "complete" message. Still won't launch. In fact, the game no longer shows up on my app store's "Installed" list. It only shows up under "All Owned." Weirdly, it *does* show up in my Windows Start menu -- but clicking on it just opens the app store.

I tried running wsreset.exe and rebooting. No change.

I'm stumped. Any ideas?

Although I haven't had any major issues with Windows 10 in quite some time, I have, in the past, had to run the procedure listed here to resolve some issues with the system: https://answers.microsoft.com/en-us/windows/forum/windows_10-update/system-file-check-sfc-scan-and-repair-system-files/bc609315-da1f-4775-812c-695b60477a93
