After reverting to a backup from before I went exploring the freeze still happens at the exact same spot on my minecart track. I even spawned in a whole different place and it still only froze right there. I think there might be something to your corrupted chunk theory. Perhaps the fix is just bordering off a restricted area for players haha

Yeah that checks out exactly with my experience. Going back to an older version isn't an option because most of my friends play on Switch, so I really hope this can be fixed...

I just posted the exact same issue sadly 😞. Is there any chance you went beyond your previously generated world and generated new chunks after updating? I suspect that's the cause on my end, since they changed world seeds in this update.
