I came here to see if anyone was having a similar issue and I saw one post but they said it was from playing offline just their inventory was deleted but I don't think that's my problem.

I was playing earlier just fine but a few minutes ago when I logged back on I was at spawn with a new map, no items in my inventory, and even my end chest was empty. All my other chests and items were still there? It's like the game registered me as a new player in my own world or something. I tried logging out then back in but nothing happened. I also tried dying to see if maybe it would drop my stuff upon death but nothing. Has anyone else heard or seen this happening?

Side note: while typing this I tried loading into my creative world and basically the same thing?? I spawned at what I assume is spawn for that world with nothing in my inventory.
