As I have stated in the original post I do not have any plugins nor addons, I also have not uploaded any worlds.

So this is a problem that I've had for around 4 days now but at the start it only refused to load some chunks and restarting would fix the issue, but yesterday when working on a megabase with a friend the server randomly stopped loading any chunks and a few seconds later crashed with both of us getting the same error message (image below). The server is on 1.17.1 with no plugins or add-ons installed, any kind of help would be greatly appreciated.
