Since 1-october-2021 Minecraft on PS4 crashes every time I enter a specific world (my personal one) or any of its copies. It doesn't happen with other worlds. I enter then after few seconds, regardless of doing something or nothing, it crashes and gives error CE-38700-8, making that months old world and its copies unplayable since yesterday. 

I uninstalled and then reinstalled the game but nothing changed.

As coincidence, the previous day (30-september-2021) has been installed an update (2.30 version for PS4). So I suspect the problem may be related to this update.
