It will break the installation, and throw file errors when MS Store attempts to reset, repair or start the game from an app tile. As well as cause damage to Windows and the Microsoft Store itself.
In addition, every few minutes or so, MS Store will attempt to re-run the program due to it thinking it restored the application, making your life a living hell if you're trying to do anything else on your computer. it will also start causing a feedback loop of the MS Store attempting to download/install/repair the game and will start backing up / re-deleting the game over and over and over and over and over and over and over again. Eating up your disk space faster than other issues.
For this reason, I petition SEGA remove the game from the Microsoft store immediately until this issue is resolved.
