I have been trying to troubleshoot this issue on my ps4pro. I had three saves 1 manual and 2 auto and these are my latest saves. Everytime I load these saves my game loads and I am about to move but a new all black load screen comes and I listen to my ps4 not work as as hard anymore like the memory was dumped or something and then after that black load screen eivor cannot move, talk to anyone or fast travel. I wish I could just be unstuck again. I tried to look over various other posts from people and the closest thing I could find was I was on that Lunden quest shadows and walls. I am loading in the city of Cent right by the drunk lady and her bowl of beer I think? I can take a video or whatever you need. Maybe you're fixing this but I just tried to fix it for like 3 hours.
