I've had issues with the Starport UI locking up, usually when opening the Contacts option. A fix I've found is to go UI Focus + Down (IE the key combo you use to get to left or right screens, except down instead of left/right. Shift + S by default), and that lets you select Starport Services again, which gets the UI working.Also a new bug happened: When logging in today, the UI of the Starport services suddenly locked up and refused to take any input. Testing revealed my controls worked in the galaxy and system maps, so the issue seems to be connected to the Starport UI.
Since I couldn't leave the locked up screen except for looking at the map and other UI-windows, I logged out and restarted the game. This fixed the issue for now but I made a ticket just in case.
