Everything In My Inventory Has Disappeared

I had got on to Minecraft as usual and all of a sudden my entire inventory was gone, I had full netherite gear but I had my netherite armor in a chest before the bug so it was still there, the world was just an average everyday survival world. And I triple checked every chest I had and i couldn't find any of my stuff so I'm sure this is a bug, please let me know if there is anyway to get my inventory back, it took me so long to get that netherite stuff
