Hi YourWorstCringe
I am Dave, an Independent Advisor, I will help you with this . . .
All Microsoft Store Games and Apps are stored in their own folder inside C:\Program Files\WindowsApps
That WindowsApps folder is the most protected folder on a Windows 10 system, and it is extremely hard to access, the reason that is so protected is to ensure the integrity of the Store Apps and Games
Microsoft strongly advice you do not change permissions on the WIndowsApps folder or any of the contained folders, you can cause all store apps and games to stop functioning and even brick Windows 10
If you want to find the exact path to the game executable:
Open Task Manager (Ctrl + Shift + Esc)
On the Processes Tab, right click any column header and turn on the Command Line column
Expand that column as much as possible
Start your game, and wait a few seconds
Go back to Task Manager and in the Command Line column, you will see the path to the game executable
