In my Multiplayer LAN game, my friends can connect to the game fine, however once they get access to the world all they can see are floating mobs and the blue sky background. There is no ground, terrain, or blocks. They also can't move or interact with any objects. We have experienced this a few times but don't have any solutions. We also do play using modded Minecraft. We don't have any problems connecting, it's just that the game is unplayable to people who log in. The computer running the LAN game runs it fine, with no issues. We are all running the game on the same WIFI connection and using Windows. When we look at our game version, it says we are using 1.15.2, but this submission page doesn't allow that input.
