After the latest update I logged into play on my son's world with him but my inventory was completely gone and I spawned in the original spawn point in this world. After returning back to the Xbox Home Screen and quitting the game "which usually fixes this issue" and reloaded the game it still had me spawn in the same spot with an empty inventory. We then had our daughter log in and it was the same, she spawned in the original spawn point with a completely empty inventory.

I lost my enchanted netherite pick axe, and sword and enchanted elytra wings and 8x shulker boxes full of items! Also all of the items I had assigned to me in the ender chest are all gone too, including another 14 shulker boxes full of items and 3 empty shulker boxes!
