I was having the login freeze and could not get it to load not matter what I did. This worked me for multiple times now, so it's an easy and quick work around hopefully! I hope it works for others. 

Simply run Ground as administrator. Did that, loaded in immediately and logged in no problem. 

Hope this helps others!

Thank you for this! I will be sure to share it with the team so they can use it to look into this, and will share with other players as a potential workaround!
