Try connecting over some other connection maybe? Try using your phone’s internet and see if it’s your connection. It might sound unrealted, since you’re using the same connection as always, but something similar had happened to me with another update. In my case, the game just wouldn’t download the in-game update. It would download through 99% and then say “the update cannot be downloaded” or something like that. There was next to nothing about that on the internet, either. So, try another connection and see if that works.
Started playing SFV a little more lately on PS4. I noticed while playing offline like when doing a combo a second or two of slow motion would happen once in a while. When searching the forums about it I only found old info on the frame dropping on PS4. Have they not fixed this yet?
