There was a problem loading this world

I frequently make backups for my worlds because of other problems that have resulted in losing my worlds and not being able to get them back. This is a new one. So last night I copied my world backed out to the main menu, turned off my controller and console, waited for it to properly switch off and finally turned it off at the wall. This afternoon when I tried to load the world I got the error message “There was a problem loading this world”. I then tried loading the backup I made and nothing happened, tried loading other worlds and again nothing happened. So I restarted the game and tried to load the backup, got the same error and still couldn’t load other worlds. Then restarted it again and loaded up a different world and it loaded in, then went to load up the problem world and got the same error. I have tried everything I usually try when other errors occur such as uninstall and reinstall, clear local saved games, reset MAC address, all do nothing and the same thing happens. Now I have previous manual backups but it is still a pain to have this happen because of the loss of progress, how can I go about fixing this problem to get the most recent version of the world back?
