Saved world causes crash in 1.13

Please do not mark unreleased versions as affected.
You don't have access to them yet.

This has happened to me too!

Thank goodness I backed it up before trying!

I will be playing 1.12.2 still until 1.13.1 or 1.13.2 comes out because 1.13 is VERY UNSTABLE!

I had the same problem.

I found out to fix the world after the error occured you can create the same world with the seed again and copy paste the regions and playerdata into the new generated world.

I am having this problem with 18w30b, copying the regions and players data into a new world with that same seed did not fix the issue for me.

I was redirected to this page and it says resolved however, it is still crashing. I don't understand what I need to do. Please do not redirect me without explaining what I'm supposed to do at the new page. Thank you
