There has been a glitch going around in the bedrock edition of minecraft, after entering the end portal a second time you take massive amounts of damage which is classed as fall damage. However there's a catch, if you have any items, they disappear. They don't drop, they don't go to the surface or anything. You also get stuck in a respawn boot where your hit box is gone and it's only one block tall. The only 2 ways to get out of this respawn glitch is:

1. Don't click respawn and let your friend push you into the end portal
2. crash minecraft
