Exact same thing has happened to me. I have the PS4 disk version with the latest patch installed. Game's auto-save files broke after a death late game. Tried deleting game and reinstalling from the disk, tried clearing the PS4 cache, tried restarting the PS4 in safemode and rebuilding the database.
All of this was suggested in a support ticket I opened with Private Division.
No luck with the save file. I was able to start a new character and load that character's files as well as load a much earlier version of the original character's files, but I'm weary to try to re-play anything when it's possible for this to happen again.
