My PS4 power cord came loose while in my Minecraft world. Now I can't load that world

My PS4 power cord came loose while in my Minecraft world. Now when I load into Minecraft all other functions work fine, but when I click the world I was in when my power cord came out—called Copy of Copy of the New New Nation—my whole system freezes. I can't select anything, go to a different world, click on a friend, nothing. I don't even get an error message, it just freezes.
