Description

When running a neoforge 1.21.1 modded server with LuckPerm installed, the players are not able to join the game.

I originally tested it on v5.4.140 and it was saying that the player data is invalid. So i tried downgrading to v5.4.139 which is the only other version available for neoforge 1.21.1. This time the "player data is invalid" error was not present but the players got stuck on the "Joining World ..." screen.

i used neoforge 21.1.127 and 21.1.133 and they both had the same outcome.

Reproduction Steps

1. Install neoforge 21.1.127 or 21.1.133
2. Install LuckPerm v5.4.139 or v5.4.140
3. Try joining

Expected Behaviour

if using the v5.4.140 you are going to see a "disconnected" error (it's the dame invalid player data in the console) or a "Invalid Player Data" error

But if using the v5.4.139 you will get stuck in the "Joining World..." screen

Extra Details

I tried removing the playerdata folder entirely or the LuckPerm config files but the issue consisted like before.

this is fixed in the latesr versions

Is it possible to get a hotfix for 1.21.1? Because i can't switch to any other version
