Happening a lot with other ea games as well. Also a lot of times for my games at least, they are left running in the background as well. Not sure if it is just for certain systems or whether it is a launcher glitch.
I'm not familiar with this version as much as I am with the console version of skates, but as it evolves currently it seems the game on PC, which skate hasn't been on for years in this space is reliant on more RAM processes than not.
Other than that, the black screen almost seem like a console launching and then the game trying to run in the background to a loading screen. Makes sense, but in a technical sense, I could see how they would do this in a earlier period in the game but if it's in the full release I'm sure they lose half of the player base too just low end systems.
