For anyone wondering where the settings for apps from the Microsoft Store are, they are either in WindowsApps, which is very locked down, but you can get there by opening your app and then opening the file path with Task-Manager.
But it's more likely that they are saved in C:\Users\[USERNAME]\AppData\Local\Packages\[NUMBERS][COMPANY].[APPLICATION]_[RANDOMDATA]\LocalCache\Local\[COMPANY]\[APPLICATION].exe_Url_[RANDOMDATA]\[VERSION]\user.config.
