There was an error loading this world, creating a world glitch

(I play on minecraft ps4) Once I was playing on a good world and my power went off which then turned off my PS4 and the world I was playing on, it then said it was corrupted and all my other worlds were also gone. I was pretty sad so I tried to make a new world but when I tried I just got a message saying 'There was an error loading this world.' sometimes it would save the world and say 0.1mb and if I clicked on it, it would just disappear. Also whenever I try to play servers/minivames my game crashes, I have tried to delete the game then reinstall it but that doesn’t help.
