Game crashes in a specific world due to a bundle in the player's inventory

After loading up the world that I've had for approximately a year, I can only move around. After opening the Inventory, opening a chest, or simply hitting "Save & Quit" on the pause menu, the game crashes, closing everything. I tried to "Fix" it via my Windows apps list, did some research, and even reset the app and Re-imported the world, losing everything else. It only happens in this specific world, though. The servers work fine, as well as other worlds. Life.mcworld
