when I enter the portal at the end, to go to the normal world I die and the game crashes

I was going to the end portal, the dragon was already defeated, I entered the end portal with no intentions because before when I entered the end I fell straight into limbo it was another bug but I didn't fall so I went back to the normal world by end portal, I came back dead and the game crashed and I couldn't play but I had to close it please ageitem this has many bugs.
