Crash in snapshot 26.1-snapshot-7 deletes diamond armor and tools during gameplay

I experienced a crash while playing snapshot 26.1-snapshot-7. Before the crash, I had:

• Full diamond armor

• Diamond tools (pickaxe, shovel, sword)

• Around [insert number] diamonds in my inventory

Everything was crafted and in my inventory. The crash occurred while I was descending toward my mining area, about halfway down.

After reloading the world:

• My diamond armor was replaced by the iron armor I had stored in a chest

• The crafted diamond tools disappeared from my inventory

• I was left with only [insert number] diamonds in my inventory

• My diamond pickaxe with enchantments (Fortune II, Efficiency III, Unbreaking III, Mending) remained intact

Error details:

• Game exited with exit code 6

Steps to reproduce:

1. Play in snapshot [insert snapshot version]

2. Craft diamond armor and tools

3. Move toward your mining area

4. Game crashes during normal gameplay (exit code 6)

5. Reload world and check inventory/chest

Expected behavior:

• Diamond armor and tools should remain in inventory/chest after a crash

• Items should not be replaced or disappear

Observed behavior:

• Diamond armor replaced by iron armor

• Diamond tools disappeared

• Inventory shows fewer diamonds than before crafting

Additional info:

• World is in single-player mode
