When a world is closed (or the game is paused in singleplayer), the game fails to save files in the world's /data/ folder if they don't already exist. This affects things like raids.dat, scoreboard.dat, any maps generated, and so on.
Steps to reproduce
Create a new world. Do things like create scoreboard objectives and open maps
Press Esc to pause the game
An error similar to the one attached should occur
When closing and reopening the world, the data will not exist. Any scoreboard objectives created previously won't exist, and previously created maps will be blank
