If you got the AppX (basically the modern msi) you could sideload it on PC, and it might be able to run natively (no emulator), but there's no known legal way to get that AppX file. The publisher essentially just chose not to release it on PC. They use the exact same Microsoft Store on both PC and Xbox. There might be some Xbox-specific APIs but I believe these fail silently on PC, so it might run but not be as stable. Xbox games from 2016-present are technically very similar to Windows 10 UWP apps. Everything here is my assumptions based on my own knowledge and some basic info on their dev sites, this could be incorrect, but for most part should give you a basic idea of how complex this is.
