Error 117 is a problem loading the story patch implementation.
Try clearing the PS4 cache: press and hold the PlayStation button on the controller, select 'Turn Off PS4', wait another 30 second after it finishes shutting down, and start it again.
If you start a new game and create a new manual save, does that work properly? Don't move up the beach when testing this, or an auto save may overwrite a save from your current playthrough.
If you start the game from a different PS4 account, if available, and start a new game, do you continue to have issues loading saves? That would give a separate set of saves.
One person (with crashes loading saves) moved their saves to a flash drive preparing to reinstall, decided to copy the latest save back to the drive to try it again, and it worked. Either there was a corrupt file there causing a problem loading any of the saves, or there was an issue with the drive space reserved for the game, and clearing it out and moving the save back fixed it.
Try doing that, and do a full uninstall, restart and reinstall if copying the latest (or one you now loaded before) save back.
