G5/Mytona changed things awhile back...they stopped using the player_backup2.prf so this file shouldn't be there anymore. The only ones used now are player.prf & player_backup.prf and are usually the same or from a very small time apart. The most important and always the most up-to-date one is the player.prf and this is the only one you need to backup. If you "right-click" (using the mouse right button) it you should get an option to "Copy". Selecting "Copy" you won't see much happening but if you then navigate away from the LocalState folder to somewhere else, say C:\SSHMBackup (create if necessary) and right-click again, you should see a "Paste" option. Select this and a copy of the player.prf should appear in the backup folder.

This seems more of a Windows store issue so it's probably then best to just uninstall the entire app and try to get it again from the Windows Store. Once you've installed, before you run it put the backup copy of the player.prf file back in the now completely empty LocalState folder. It's not essential that you do this as your PC device id should be recognised by the server and you'd get a restart offer, but it avoids any temporary issues with network connections that could possibly throw a wrench in the works getting the game back from the servers.
