Login problem with up studio 3 version 3.3.4

i can’t seem to login in up studio 3 version 3.3.4
every time i try to login it keeps loading or it says check internet connection.
i can log in with up studion 2.
my hope is when i get to log in that i can get to all the settings cause most of it is grayed out.
most of the things i can find online don’t add up to the current build of up studio 3.
so if there are any smart people who can help me out it would be greatly apreciated
