When an armory cabinet full of armor and tools is broken, I get kicked out of the game and can't log in again. Every time I try to log in, I see this error again and can't log in. This forces any player who experiences this to go back to backup. But the problem is that there is no way to destroy that armory cabinet. When you break it with a normal pickaxe, the game crashes, and when you try to carry it with a carry on, the game crashes.

When this occurs on a server, the item kicks the player who loads it in. It does not crash the server, interestingly. Thus, if desired, to work around this issue, the world could be loaded to a server, load the chunk, and allow the item to expire. The armory cabinet would only be loaded if in spawn chunks or while a player were active. Alternatively, you can /forceload the chunk and let it expire that way.

This was the entity data of my dropped armory cabinet: https://pastecode.io/s/f8qkzwbo

However, this is obviously not the best route. The cabinet might hold valuable items. At the very least, you can retrieve the item data this way.
