Attempted to enter the nether portal to respawn the ender dragon. Upon entering the portal, the game froze on lpading terrain screen.  After 15 minutes, I closed the application on the ps4 and restarted the game.  Upon respawning,  all of my exp levels, armor, and inventory was gone.  Armor was enchanted Netherite.  In front of the End portal, for some reason a nether portal was assembled and lit, even though indidnt even have obsidian on me.  Was able to go through the end portal and come back with no problem after that, but everything I had on me was gone.
