Fell through the spawned obsidian when I went through the end Portal.

I was playing a survival world going into the end so I could fight the end dragon and platinum the game. Unfortunately the game seems to have bugged out and I fell through the spawn platform. I had full enchanted netherite armor, sword, 2x pickaxe, axe, hoe, bow, trident, etc. I LOST EVERYTHING. This is not okay. I spent many hours collecting this. Is there anyway yall could give me that stuff back since it was the games fault for not spawning me correctly? Without using cheats. I'm trying to Plat the game.
