Exact same Issue as MCPE-62944 but on Java Edition 1.19.

I am incredibly angry as my 4 Shulker boxes are now deleted from the world and I do not remember what they contain. Now I must cheat to get my Shulker boxes and items back.

When I rejoined my world after the crash, It spawned me in an earlier rejoin area, but all the blocks I mined between then were already mined. Like a player info error of some sort.
