dying automatically from entering a world and making world copies doesnt make it stop the "dying" It does it almost no matter what

dying automatically from entering a world and making world copies doesnt make it stop the "dying". Seriously, I already reported this but said was duplicate but here's more to it. Even though I made world copies after every time I did this it still thinks that I died. SO what am I to do, just hope everything works out!? I don't mean to be mean but I lost everything and it was diamonds, a heart of the sea, and potions! Please help... Only twice the world copy worked and that's after doing the world copy for multiple times.
