Situation Summary:
I play two player split screen on the Xbox S with my mom(I play as player 2). Within the game through the pause screen I accessed the Dressing Room to change an aspect of the Bases part of my skin.

Expected Result:
The Bases tab opens up and allows me to make the desired changes.*

Actual Result:
Upon opening the tab it crashes the game. When reopening the game I had lost all of the items in my inventory and the enchanted netherite armor I was wearing. The thing that was odd as that I had still retained all of my experience levels and my previous location.

How To Reproduce:
1. Have Player One log into Minecraft and world.
2. Once in the world, grab a second controller and sign in the 2nd play only when Minecraft gives the prompt to use the "3 Line Button" that's located on the remote.(do not log in player 2 before hand)
3. Through the in game pause screen open the dressing room and change any customization.

Side Notes:
I have experienced when reproducing the bug it is inconsistent with getting it to crash. And I have had an extremely difficult time recreating it to delete my stuff on top of the crash.
