Same exact thing. Happened just an hour ago. 30+ crafts, on year 34. Logged out last night after landing an airplane on Laythe, logged in this morning and the save just won’t open, I click X and it freezes the whole game, nothing can fix it. I’ve tried loading cloud backups, USB backups, reinstalling the game, restarting my PS4, none of it works. It’s a shame they’ve put so little work into console KSP, it’s almost 2 years behind in real content updates, the bugs and crashes are nearly unbearable, I’ve never been able to get through a single session without a crash. It’s an awful experience.
