My understanding–someone correct me if I’m wrong–is that Microsoft, being Microsoft, locks up the actual contents of the games you “buy” from them. So it is difficult if not impossible to mod games from the Microsoft Store, and that includes using Vorpx with them.
For instance, I just bought Deep Rock Galactic from the MS store, and it won’t work with vorpx.
The lesson here is: Don’t buy games from the Microsoft Store, because you won’t really own the contents you paid for. MS will still keep those contents under lock and key.
Yes, I now Game Pass is more of a rental service, but the same still applies.
