I updated a pack to a newer version and loaded into my old world to host it via LAN but when my friend tried connecting it said that data failed to sync.
It was fine before the pack update and i have no idea what caused this since making a new world DID fix the issue. only for it to break again after not changing anything.
this is my latest log that generated in the folder:

i have no idea why it would break by literally doing nothing and have no idea how to fix it beside making a new world and losing all the progress.
