Realm crashing and resetting 10 mins possible source

In the image, the bottom chest is actually a double chest but half is invisibile. When I try to interact with it, the game crashing and resets back 10 mins. Idk how it turned invisible, but I was putting my nether things in there. Also some beds near there became invisible as well.

The realm also crashed a few other times when I wasnt near that chest, but I feel like the possible source are all chests.
