Do a HARD RESET !!!
To do that, hold the power button for 10 sec. while the system is on. The system will turn off.
When you hit the button again, it will start and display the green start-up screen.
All your data is preserved, but cache is cleared and some settings are reverted and log-in or game start issues should be resolved.
I assume this is for Fallout 4....?
Moving thread there.
