I too am indeed experiencing this incredibly annoying problem, the game works fine for me on pc but on console it is a whole other world, game freezes after pressing start at the main menu. Have annoyingly reinstalled twice, once on external and internal, both which took almost an entire day to do as this game is nearly 100GB of data. This is very ridiculous, seeing as how far back this thread goes it's absolutely mind blowing that the issue hasn't been resolved, it clearly cant be entirely on our end if this many people are going through the same problem. Although I can confirm it takes 5-10 mins of waiting and it will come back but the problem shouldn't be present at all.
