How to Reset
Right click on the game -> Properties -> uncheck the cloud save option (not sure if this is necessary but I did to make sure it doesn’t download the cloud save files).
Then go to your main partition:
And delete the data in there.
If you can’t see the AppData you need to enable visibility of hidden folders in the windows settings.
Then the game should be reset. Don’t forget to re-activate the could save option if you want it and re-synch.
Note: I launched the game after deleting the files without reactivating cloud first.
