I fell into void when i shouldnt

i fell into the void when i shouldntve, i had full netherite gear right, and i went throught the end portal, and the obsidian that you spawn on didnt render, so i just fell into the void and lost so much crap, i had my valuables shulker on me aswell, so i lost all my diamonds, iron, netherite gear, and my elytra aswell as my backup elytra, so i lost everything that i grinded for in this world, and im kinda annoyed and angry, fix your game please
