It seems that my world is unable to load, as the loading screen green bar is stuck when it reaches the end, with the ‘Generating world’ on it. It didn’t seem like it froze, as the music and tips are still functioning.
Edit:
After some searching, I found out that many other players are having the same issue, as they all left in the nether/end dimension. I left my world in the nether dimension as well.

@Auldrick Will there be any way to restore my current world with the issue?
I am also having this problem. The loading bar will almost completely fill, ending at the "generating world". The game doesn't freeze, it keeps playing the music and scrolling through tips. I can still edit the world and make copies of it, but neither it nor any copies actually get loaded up. I've seen some other people reporting similar problems on other websites, and like me, it began when they tried to load up the save after exiting in the nether.
