Entering a specific chunk crashes my game and deletes items created / used between autosave.

I'm playing a 1.18 prerelease Hardcore world, and every time I enter a specific chunk in my world, I get this error:

" The game crashed whilst exception in server tick loop
Error: java.util.concurrent.CompletionException: z: Feature placement
Exit Code: -1 "

Then re-log and lose whatever items I used during the lost time (in this case, fence posts and golden apples).
