i lost all my loot to a BUG a THE END ISLANDS

I was at the end islands and lost all my loot, because I was in my inventory hovering over 1 simple island. 1668 blocks away from the place I had to go to and in my inventory 5 seconds in I was falling and I looked at my elytra. I just put it on when I started flying and so I pressed space bar I was still falling and I looked in my inventory by the time I knew my elytra was fine i DIED JUST THERE.

Please help me how I can get back my loot. Thank you,
